Qo'l yuklash - Handloading - Wikipedia

Zamonaviy darboğazning tarkibiy qismlari miltiq patron. Yuqoridan pastgacha: mis ko'ylagi o'q, tutunsiz kukun granulalar, ramkasiz guruch korpusi, Bokschi uchun primer.

Qo'l yuklash yoki qayta yuklash qilish jarayoni qurol patronlar yoki chig'anoqlar individual komponentlarni qo'lda yig'ish orqali (ish, astar, yoqilg'i va snaryad kabi o'q, shilliqqurt yoki otilgan ) sotib olish o'rniga ommaviy yig'ilgan, zavod tomonidan yuklangan o'q-dorilar.^[1]

Atama qo'l bilan yuklash bu umumiyroq atama, chunki u har qanday manbadan komponentlar yordamida o'q-dorilarni qo'lda yig'ishni nazarda tutadi. Qayta yuklanmoqda aniqroq qayta ishlatilgan qutilar yoki ilgari o'q uzilgan o'q-dorilarning snaryadlari bilan yuklarni yuklashga tegishlidir. Bu atamalar ko'pincha bir-birining o'rnida ishlatiladi, chunki texnikalar asosan yangi yoki qayta ishlangan komponentlardan foydalanishda bir xil bo'ladi. Farqlar ishlarni yoki chig'anoqlarni tayyorlashda yotadi; umuman yangi butlovchi qismlar yuklashga tayyor, ilgari yoqilgan komponentlar ko'pincha qayta yuklashga tayyor bo'lishdan oldin tozalash, sarflangan astarlarni olib tashlash va ehtimol qayta tayyorlash / o'lchamlarini o'zgartirish kabi qo'shimcha protseduralarga muhtoj.^[2]

Qo'l yukining sabablari

Iqtisodiyot, aniqlik, ishlash samaradorligi, o'q-dorilarning etishmasligi va sevimli mashg'ulotlariga bo'lgan qiziqishlar - bu ikkalasini ham qo'lda yuklash uchun umumiy turtki. patronlar va zarbalar. O'q-dorilarni qo'lda yuklash foydalanuvchidan voz kechadi ish haqi tijorat ishlab chiqarish liniyasi ishchilar, xarajatlarni faqat komponentlar va jihozlarni sotib olish xarajatlariga kamaytiradi. Ishlatilgan gilzalarni qayta yuklash o'q otuvchiga pulni tejashga yordam beradi yoki ma'lum bir byudjet doirasida o'q otuvchini ko'proq (va yuqori sifatli) o'q-dorilar bilan ta'minlaydi. Qayta yuklash vaqti-vaqti bilan otishma uchun arzon bo'lishi mumkin, chunki vaqt talab etiladi xarajatlarni qoplash kerakli asbob-uskunalardan, ammo ko'p o'q otganlar vaqt o'tishi bilan tejashni ko'radilar, chunki jez patron qutisi yoki o'qotar qurol qobig'i (eng qimmat komponentlar) almashtirishni talab qilishdan oldin ko'p marta (tegishli texnik xizmat ko'rsatish bilan) qayta ishlatilishi mumkin. O'qlar / o'qlar va astarlar, shuningdek, ommaviy sotib olayotganda chegirmali narxlardan bahramand bo'lishlari mumkin.

Iqtisodiyotdan tashqari, o'q-dorilarning ishlashini sozlash ham umumiy maqsaddir. Ovchilar o'ziga xos o'q bilan patronlarni xohlashi mumkin terminal ishlashi. Maqsadli otishmalar erishish mumkin bo'lgan eng yaxshi narsani qidiring aniqlik, shuningdek, eng izchil traektoriyalar (ya'ni eng yaxshi aniqlik). Ov miltig'i ixlosmandlari tijorat inventarizatsiyasida mavjud bo'lmagan maxsus turlarni har qanday narxda amalga oshirishi mumkin. Ko'pgina yuk ko'taruvchilar, odatda, aniqlik uchun o'zlarining patronlari va chig'anoqlarini o'ziga xos o'qotar qurollariga moslashtiradi: ular patron qutilari yordamida aniq o'q-dorilarni yig'ishlari mumkin. olov hosil bo'ldi ga eng mos kelish uchun kamera ma'lum bir qurol.^[3]

Handloaders moslashuvchanlikka ega aniq qilib sozlash Yonilg'i quyish moslamalari ularning maqsadlariga eng mos keladi. Masalan, otishni o'rganuvchi yumshoqroq qilish uchun ov miltiqlari uchun kam quvvatli o'q-dorilarni yuklashi mumkin.orqaga qaytish To'liq quvvatli ovchini yaxshi o'rganishdan oldin, orqaga chekinadigan ovchilarni rag'batlantirish uchun yumaloq. Bundan tashqari, yuk ko'taruvchilar uchun bu odatiy hol emas kuchaytirilgan o'q-dorilar (ya'ni "issiq yuklar") yuqori bo'lsa tumshug'i tezligi (shuning uchun tekisroq traektoriyalar) istalgan. Ko'plab yangi boshlang'ich ovchilar bir necha ov mavsumida ko'payib ketadigan maxsus maqsadli miltiqni sotib olish o'rniga, bitta miltiqni shu vaqtga qadar kuchliroq o'qlar kerak bo'lguncha va qo'lga kiritilguncha maxsus qo'l bilan o'q bilan ishlatish mumkin. Qo'llarni yuklashning ixtisoslashgan texnikasidan foydalanish ko'pincha xarajatlarni tejashga imkon beradi, ayniqsa, agar oilada ovchi to'liq quvvatli miltiqqa ega bo'lsa va oilada yangi ovchi sportni o'rganishni xohlasa. Ushbu uslub shuningdek, ovchilarga turli xil ovlarni ovlash uchun bir xil miltiq va kalibrdan foydalanishga imkon beradi.^[4]

Ushbu qurollarni tez-tez o'qqa tutmoqchi bo'lgan eskirgan qurol-yaroqlarni yig'uvchilar qo'llarini yuklashlari kerak, chunki tegishli patronlar yoki o'q otish qobiqlari endi savdo sifatida ishlab chiqarilmaydi.^[4] Handloaders shuningdek, hech qanday tijorat ekvivalenti mavjud bo'lmagan kartridjlarni yaratishi mumkin mushuk patronlari,^[5] balistik ko'rsatkichlar yaxshi ekanligi isbotlansa, ba'zilari keyinchalik asosiy qabulga erishishi mumkin. Har qanday sevimli mashg'ulotda bo'lgani kabi, qayta yuklash jarayonidan lazzatlanish ham eng muhim foyda bo'lishi mumkin.

Savdo o'qlarining takroran etishmasligi, shuningdek, patronlar va o'q otish qutilarini qayta tiklash uchun sababdir. Tijorat ta'minoti quriganida va do'konda sotib olingan o'q-dorilar har qanday narxda mavjud emas, chunki o'z patronlari va o'q otish qobig'ini qayta yuklash imkoniyati, tanqislikka qaramay, o'q otishni davom ettirish imkoniyatini beradi.

Uch jihat bor ballistik: ichki ballistik, tashqi ballistik va terminal ballistikasi. Ichki ballistika deganda, o'q otish paytida va undan keyin, ammo o'q tumshug'i chiqmasdan oldin qurol ichida sodir bo'ladigan narsalar tushuniladi. Qo'lni yuklash jarayoni tegmaslik o'q og'irligi va dizayni tanlab olish va o'qning tezligini maqsadga moslashtirish orqali ishlab chiqarishning yaxshilangan mustahkamligi orqali aniqlik va aniqlikni oshirishi mumkin. Qayta yuklangan har bir kartrij har bir komponentni partiyadagi qolgan patronlar bilan yaxshilab moslashtirishi mumkin. Guruch qutilar hajmi, vazni va kontsentratsiyasi bo'yicha, o'qlari og'irligi va dizayni bo'yicha, chang zaryadlari og'irligi, turi, kassa to'ldirilishi (zaryad bilan to'ldirilgan ish hajmining umumiy hajmi) va qadoqlash sxemasi (granulalarni qadoqlash xususiyatlari) bo'yicha mos kelishi mumkin.^[4]

Ushbu muhim narsalardan tashqari, kartrijni yig'ish uchun ishlatiladigan uskunalar ham uning bir xilligi / izchilligi va optimal shakli / o'lchamiga ta'sir qiladi; o'ladi patronlarni kattalashtirish uchun ishlatiladigan qurolning kamerasiga mos kelishi mumkin. Zamonaviy qo'l yuklash uskunalari qurol egasiga yangi o'q-dorilarni o'ziga xos o'qotar qurolga moslashtirishga imkon beradi va tijorat o'qlari ishlab chiqaruvchilari ishlashi kerak bo'lgan nisbatan keng toleranslarni ancha yaxshilaydigan aniq toleranslarni aniqlaydi. Miltiq kabi eng aniq aniqlik talab qilinadigan joyda skameykada otish, qo'lni yuklash muvaffaqiyatning asosiy shartidir.^[4]

Uskunalar

Hornady bir martalik qayta yuklash pressini ("O" ramkasi) o'lik bilan

Qo'lni yuklash uchun asosiy jihoz bu bosing. Press - bu birikmani ishlatadigan asbob kaldıraç holatlarni a ga surish o'lmoq yuklash operatsiyalarini bajaradigan.^[6] Ko'rgazmalar oddiy, arzon bir bosqichli modellardan tortib to qo'lning har bir tortilishi bilan ishlaydigan murakkab "progressiv" modellarga farq qiladi. yig'ish liniyasi daqiqada 10 turgacha bo'lgan stavkalarda.^[7]

Qayta yuklash uchun arzon "tong" asboblari 19-asr o'rtalaridan boshlab qo'llanila boshlandi. Ular katta penselga o'xshaydi va kalibrga xos bo'lishi mumkin yoki almashtiriladigan matritsalarga ega bo'lishi mumkin.

Matbuot

Qayta yuklash presslari ko'pincha alfavit harfi bo'yicha eng ko'p o'xshash toifalarga bo'linadi: "O", "C" va "H". O'qni almashtirish funktsiyalari uchun va oddiygina qayta yuklash uchun matritsadan foydalanish uchun mos bo'lgan eng mustahkam presslar "O" turiga kiradi. Og'ir po'lat bu presslarda bitta matritsani to'liq yopadi. Hammasi uchun bir xil darajada kuchli presslar, o'qni almashtirishdan tashqari, ko'pincha "C" harfiga o'xshaydi. Ham po'lat, ham alyuminiy konstruktsiyasi "S" presslari bilan ko'rinadi. Ba'zi foydalanuvchilar "O" presslaridan ko'ra "C" uslubidagi presslarni afzal ko'rishadi, chunki "C" presslarida patron og'ziga o'qlarni joylashtirish uchun ko'proq joy mavjud. To'plamsiz ishlatishga mo'ljallangan Shotshell uslubidagi presslar, har bir o'q otish paneli yoki kartrijni qayta yuklash uchun navbatdagi tortishish qobig'iga yoki kartrijga tushishdan oldin shtamplar bo'ylab aylanib o'tish odatda "H" harfiga o'xshaydi.^[6]

Odatda "O" yoki "C" turdagi bitta bosqichli presslar eng sodda. Ular bir vaqtning o'zida bitta ishda bir qadamni bajaradilar. Bitta bosqichli pressdan foydalanilganda, holatlar partiyalarga yuklanadi, har bir patron uchun har bir partiyada birma-bir qadam qo'yiladi. Partiyalar kichik, bir vaqtning o'zida taxminan 20-50 ta holatda saqlanadi, shuning uchun partiya hech qachon qisman tugallangan holatda qoldirilmaydi, chunki yuqori namlik va yorug'lik kukunni buzishi mumkin. Yagona pog'onali presslar odatda yuqori aniqlikdagi miltiq patronini yuk ko'tarish uchun eng ko'p ishlatiladi, ammo barcha patron turlarini yuqori aniqlikda qayta yuklashda va oxir-oqibat progressiv pressda ko'p sonli lentalarni ishlab chiqarish uchun yuklarni ishlashda (yuklash retseptlarini ishlab chiqishda) foydalanish mumkin. .^[6]

Turet presslari, odatda "C" turiga, bir bosqichli presslarga o'xshaydi, lekin bitta patron (yoki ba'zan ikkita kartrij) uchun barcha shtamplarni bir vaqtning o'zida o'rnatishga ruxsat beramiz, har bir matritsa o'rnatiladi va qulflangan halqalar bilan to'g'ri qulflanadi bir vaqtning o'zida matbuotga. Partiya operatsiyalari bitta sahnada bosilgandek bajariladi, ammo matritsalarni almashtirish uchun minorani shunchaki aylantirib, boshqa matritsani joyiga qo'yadi. Turretli presslar bir pog'onali presslar singari ishlashiga qaramay, ular individual o'liklarni to'g'ri joylashtirish uchun zarur bo'lgan o'rnatish vaqtining ko'p qismini yo'q qiladi.^[6]

Progressiv presslar bir vaqtning o'zida bir nechta chig'anoqlarni boshqaradi, qo'lning har bir tortilishi bir vaqtning o'zida barcha holatlarda bitta qadamni bajaradi. Progressive presslar barcha kerakli matritsalarni, shuningdek, chang o'lchovi va primer ozuqani ushlab turadi, shuningdek, ortiqcha yoki ortiqcha to'lovlarni oldini olish uchun kukun darajasi tekshiriladigan qo'shimcha stantsiyani ham o'z ichiga oladi. Progressiv presslarda ko'pincha yuzlab holatlar yuklanishi mumkin bo'lgan ish lentalari mavjud bo'lib, foydalanuvchi faqat o'qni tegishli ishning og'zi ustida ushlab turishi va qo'lni tortib olishi kerak.^[7]

Primer cho'ntaklar avtonom, skameykada o'rnatiladigan, ixtisoslashgan presslar yoki, muqobil ravishda, "O" uslubidagi qayta yuklash pressiga o'rnatilishi mumkin bo'lgan maxsus shpal anvil matritsasi va maxsus qobiq ushlagichi bilan katta yoki "O" tugmachasidagi holatga kiritiladigan kichik primer cho'ntak plashchasi, odatda normal qobiq ushlagichi joyiga bosiladi. Shunday qilib, har xil turdagi harbiy ishlarda ham kichik, ham katta primer cho'ntaklar astar cho'ntak burmalarini olib tashlash uchun to'g'ri ishlov berilishi mumkin. Ikkala turdagi press yordamida ularni qayta yuklashda harbiy patronlarda topilgan halqa qisqichlarini yoki pichoq qisqichlarini olib tashlash mumkin. Dastlabki cho'ntak qisqichlarini olib tashlash uchun matkaplar presslar bilan bog'liq emas, bu esa harbiy ish uchun primer cho'ntak qisqichlarini olib tashlash uchun pressdan foydalanishga alternativa.

Shotshell presslari

Shothell presslari odatda "H" konfiguratsiyasining barcha funktsiyalarni bajaradigan yagona bo'limi bo'lib, faqat bitta o'q otishni o'rganuvchini qayta yuklashga bag'ishlangan. Shothellni qayta yuklash kartrijni qayta yuklashga o'xshaydi, faqat o'q o'rniga, tayoqchani va o'q o'lchovidan foydalaniladi va o'qni yuklagandan so'ng, qobiq mahkamlanadi. Har ikkala 6 va 8 marta burmalash mos ravishda qog'oz korpuslari va plastik korpuslar uchun ishlatiladi. Xuddi shu tarzda, rulonli qisqichlar metall, qog'oz va plastmassa korpuslar uchun ishlatiladi. Shotshell yuklagichida qobiqning o'lchamlarini o'zgartirish, changni o'lchash, tayoqchani yuklash, o'qni o'lchash va qobiqni burish uchun stantsiyalar mavjud.^[8] Zamonaviy plastik otishni o'rganish qobig'ining arzonligi va o'qqa tutilgan chig'anoqlarni qayta yuklashning qo'shimcha murakkabligi sababli, o'q otishni o'rganish bilan patronni yuklash juda mashhur emas.^[9] Masalan, miltiq va to'pponcha patronlarini qo'lda yuklashdan farqli o'laroq, bu erda har xil ishlab chiqaruvchilarning barcha turli xil qismlari (qutilar, gaz cheklari, chang, primerlar va boshqalar) odatda bir-birining o'rnini bosishi mumkin, o'q otish qobig'i odatda o'q otiladigan qutilarning alohida markalari uchun yuklanadi (korpus deb ataladi) ) faqat bitta o'ziga xos marka wad, shot krujka (agar ishlatilsa), astar va kukun bilan, o'q otish qobig'ini qayta yuklashning murakkabligi va qiyinligini yanada oshiradi. Komponentlarni almashtirish xavfsiz deb hisoblanmaydi, chunki faqat bitta komponentni o'zgartirish, masalan, astar markasi bosimni 3500 PSI ga oshirishi mumkin, bu esa SAAMI bosim chegaralaridan oshib ketishi mumkin. Shothellarni qayta yuklash, qo'ziqorin bo'lmagan tarkibiy qismlarga ega retsept bo'yicha aniqroq bajarilishi kerak. Shothell-ni qayta yuklash mashhur bo'lib qolsa-da, ov mavsumi oldidan ovchilarni ov itlarini avtomat o'q otish ovoziga moslashtirishga o'rgatish uchun ishlatiladigan arzon narxlardagi "poppers" ni tayyorlashda, masalan, tushirilgan qaytarishni ta'minlash kabi ixtisoslashgan ov miltig'ini tayyorlash uchun mo'ljallangan. snaryadlarni o'qqa tutish, yaxshi o'q otish naqshini olish yoki tijorat maqsadlarida yuklangan o'q otish qobig'ida mavjud bo'lmagan boshqa yaxshilanishlarni yoki xususiyatlarni har qanday narxda taqdim etish uchun, masalan, eskirgan o'q otish plyonkalarini guruch korpuslari bilan yuklashda, endi tijorat maqsadlarida ishlab chiqarilmaydigan o'q otish plyonkalari uchun.

Miltiq va to'pponchani qayta yuklaydigan presslar odatda bitta kalibrli patronni qayta yuklashga bag'ishlanmaydi, garchi ular bo'lishi mumkin bo'lsa ham, kerak bo'lganda turli xil patronlar kalibrlarini qayta yuklash uchun tuzilgan. Bundan farqli o'laroq, o'q otish moslamalari ko'pincha bitta o'q otishni o'rganish moslamasini, masalan, 12 o'lchovni qayta yuklash uchun tuzilgan va kamdan-kam hollarda boshqa o'q otish qobig'ini qayta yuklash uchun qayta tuzilgan, chunki barcha yangi plyonkalarni, o'q otishni o'rganish va O'q otish moslamasida o'lchov moslamalarini almashtirish uchun talab qilinadigan kukunli burg'ulash ko'pincha yangi o'q otish moslamasini sotib olish narxidan oshib ketadi, chunki o'q otish moslamalari odatda bitta o'lchash moslamasini yoki o'q otishni o'qini qayta yuklash uchun ishlab chiqarilgan zavoddan keladi. Demak, ishlatilgan o'q otish qobig'ining har bir o'lchagichi yoki teshigini qayta yuklash uchun maxsus o'q otish moslamasidan foydalanish odatiy holdir. Xuddi shu tarzda, so'nggi bir necha yil ichida o'q otish qobig'ini qayta yuklash uchun o'qning narxi ham sezilarli darajada oshdi, masalan, 0,50 dollar / funt atrofida tayyor bo'lgan qo'rg'oshin o'qi. (2005 y.) hozirda bir funt uchun 2,00 dollarga yetmoqda (2013.) Qo'rg'oshin otishni o'rganish narxining katta o'sishi tufayli 12 o'lchovli o'q otishni o'rganish va arzon narxlardagi 12 o'lchovli o'q otishni o'rganish usulini qayta tiklash iqtisodiyoti faqatgina ishlab chiqarishni boshlaydi yiliga 50 mingdan ortiq turni o'qqa tutishi mumkin bo'lgan yuqori hajmli otishmalar uchun iqtisodiy ma'no. Aksincha, odatda arzon narxlardagi, reklama narxlarida mavjud bo'lmagan o'q otish qobig'ini qayta yuklash, masalan .410 teshik, 12 ga. 16 ga, 20 ga va 28 ga ga teng bo'lgan shilimshiqlar ancha kam miqdorda, ehtimol yiliga atigi 3-5 quti qobiq ichida qayta yuklash uchun tejamkor bo'ladi. Qayta yuklash .410 teshik, 12 ga. slaga, 16 ga., 20 ga va 28 ga. Shuning uchun snaryadlar nisbatan keng tarqalgan bo'lib qolmoqda, aksincha, 12 o'lchovli o'q otishni o'rganishni qayta tiklashdan ko'ra ko'proq reklama do'konlari odatda ko'plab chakana savdo do'konlarida mavjud. Ushbu kichikroq teshik va o'lchovli o'q otish qobig'i, shuningdek, qo'rg'oshin o'qi narxining tez ko'tarilishining ta'sirini pasaytirib, qo'rg'oshinni juda kam tortishni talab qiladi. AQSh va Kanadaning Federal ko'chib yuruvchi parrandalarni ovlash paytida qo'rg'oshin otishni o'rganish qobig'idan foydalanishni taqiqlashidan kelib chiqqan holda po'latdan yasalgan otishni o'zgartirish sanoati, o'q otish qobig'ini qayta yuklashga ham ta'sir ko'rsatdi, chunki maxsus o'q otish moslamasida otish paneli va kukun burmasi ham har bir korpus uchun o'zgarishi kerak. turi qayta yuklangan va o'q otish qobig'ini qo'rg'oshinli o'q bilan qayta yuklash uchun ishlatilgandan farq qiladi va bu o'q otishni qayta tiklashni yanada murakkablashtiradi.

So'nggi paytlarda qo'rg'oshin zarbasi narxlarining keskin ko'tarilishi bilan, o'q otish plyonkalarida katta o'zgarish ham yuz berdi. Aynan shu narsa, yuqori o'lchovli 12 o'lchovli o'q otuvchilar orasida an'anaviy 1-1 / 8 ozni yuklashga o'tish. tortishish hajmi 7/8 ozgacha. tortilgan yuklar yoki hatto 24 gm. (Xalqaro deb nomlangan) tortishish yuklari sodir bo'ldi. 1-1 / 8 oz. har bir o'q otish uchun 25 funt sterlingli qo'rg'oshin zarbasi atigi 355 ta o'q otishni boshlashi mumkin. 7/8 oz. Har bir tortishish uchun 25 funt sterling 457 ta o'qni qayta yuklashi mumkin. Har bir tortishish uchun 24 grammdan, 25 funt sterlingli o'q taxminan 472 ta o'q otishni o'rganishi mumkin. Sanoat standartidan 117 ta chig'anoq tomonidan o'qqa tutilgan 25 funtlik qo'rg'oshin sumkasidan qayta yuklash mumkin bo'lgan korpuslar sonini cho'zish qo'rg'oshin o'qi narxining katta o'sishini yumshatishga yordam berdi. Ushbu o'zgarish, shuningdek, stend va tuzoq kabi o'q otish sport turlari bo'yicha ballarning minimal o'zgarishiga olib keldi, bu faqat baland ovozli o'q otuvchilar orasida 24 gm o'q otishga o'tishni tezlashtirdi. ularning kam miqdordagi zarbalari bilan tortishish.

Yaqinda Qo'shma Shtatlarda (miltiq va to'pponcha o'q-dorilarining barcha turlari orasida) 12-o'lchovli o'q otish qurollarining 2012–2013-yillardagi taqchilligi bilan, 12-o'q otishni o'rganish qurollarini qayta tiklash ommalashganligi keng tarqalib ketdi. International 24 gm maydonidan foydalanish. 12 o'lchovli chig'anoqlar ularni kichik o'yinlarda samarali ekanligini isbotladi, shu bilan birga o'q otish sumkasidan mumkin bo'lgan qayta yuklanishlar sonini ko'paytirdi va keyinchalik ular kichik ovni ovlash bilan mashhur bo'lishdi. O'q otilgan snaryadlar odatda kamida 5 marta qayta yuklanganligi sababli, engil yuklangan snaryadlar uchun 15 martadan yuqoriga ko'tarilishi mumkin bo'lsa-da, bu 24 gm maydondan foydalanishga o'tish. yuklar ovchilar uchun o'q-dorilar etishmasligini kamaytirishga yordam berdi.

Shotshell presslari odatda tortishish va changni aniq miqdorini tushirish uchun zaryad satridan foydalanadi. Odatda, bu zaryad satrlari o'zlarining quvvatlarida aniqlanadi, masalan, 1-1 / 8 oz darajasida bitta zaryadlash paneli. qo'rg'oshin o'qi, o'zgaruvchan chang pufakchasi bilan, har xil turdagi kukunlarni aniq o'lchov bilan belgilangan miqdorini takroriy ravishda tushirishga imkon beradi (masalan, MEC.) Boshqa tomondan, ba'zi bir zaryad majmuasi ikkala tortishning har xil belgilangan miqdorini tushirish uchun burmalarni qabul qilish uchun burg'ulashadi. kukun (masalan, Texan.) Yuqori darajadagi egiluvchanlik uchun, shuningdek, mikrometrlari bilan belgilangan miqdordagi kukun va o'q otadigan universal zaryad panjaralari mavjud; bular bir xil miqdordagi kukun va zarbani tanlashga qodir va bir nechta nashr etilgan retseptlardan ko'proq yuklaydigan, ayniqsa, ko'plab nashr etilgan retseptlar bilan tajriba o'tkazishni istaganlar orasida ishlaydigan yuk ko'taruvchilar uchun mashhurdir. Ruxsat etilgan zaryad majmuasi qo'rg'oshin yoki po'lat zarbasi uchun baholanadi, lekin ikkalasi uchun ham emas. Boshqa tomondan, universal zaryad panjaralari sozlanishi bilan qo'rg'oshin yoki po'latdan yasalgan zarbani qayta yuklashga qodir.

To'pponcha va miltiq hamkasblari singari, o'q otish moslamalari ham bir bosqichli, ham ilg'or navlarda mavjud. Bir oyda taxminan 500 martadan kam o'q otadigan va ayniqsa, oyiga 100 dan kam snaryad o'q uzadigan otishmalar uchun bir bosqichli matbuot ko'pincha etarli deb topiladi. Oyiga ko'p sonli snaryadlarni otayotgan otishmalar uchun ko'pincha progressiv presslar tanlanadi. Bir bosqichli press odatda taxminan bir soat ichida 100 tanani qayta yuklashi mumkin. Progressiv presslar odatda soatiga 400 yoki 500 korpusdan yuqoriga ko'tarilishi mumkin.

Shotshell presslari ko'pincha ommaviy bo'lmagan rejimlarda ishlaydi. Ya'ni bitta korpus ko'pincha kamsitiladi, shaklini o'zgartiradi, astarlanadi, kukun bilan to'ldiriladi, vintni siqib qo'yadi, o'q bilan to'ldiradi, oldindan qisib qo'yadi va keyin olib tashlashdan oldin yangi korpusga o'raladi va yangi korpus qo'yiladi. stantsiyadagi otishni o'rganish bosimi. Bir bosqichli pressda tez-tez ishlatiladigan muqobil, biroz tezroq usul - 5 ta kassada ketma-ket parallel ravishda ishlash, ammo bitta ishlov berilgan korpus bitta pog'onada mavjud bo'lgan 5 ta stantsiyaning har birida joylashgan. Shothell tugmachasini bosib, tayyor strelka qobig'ini 5-stantsiyadan qo'lda olib tashlangandan so'ng, ishlov berish paytida yangi korpusni qo'shishdan oldin, ishlov beriladigan 4 ta korpusni keyingi stantsiyaga (1 dan 2, 2 dan 3 gacha, 3 dan 4 gacha, 4 dan 5 gacha) olib boring. (stantsiya 1) joylashgan joy. Shothelni qayta yuklashning har ikkala usuli ham avtomat va miltiq patronlarini bitta bosqichli pressga qayta yuklashda ishlatiladigan odatiy amaliyotdan farqli o'laroq, ular odatda tez-tez ishlaydigan rejimlarda amalga oshiriladigan ommaviy rejimlarda amalga oshiriladi. Keyingi ishlov berish bosqichiga o'tishdan oldin, bir vaqtning o'zida 50 yoki 100 ta patron. Ushbu farq, asosan, bitta stantsiyali kartrij pressidan farqli o'laroq, bitta stantsiyani bir vaqtning o'zida ishlatish uchun 5 ta stantsiyani bir vaqtning o'zida ishlatish imkoniyatiga ega.

Umuman olganda, o'q otishni o'rganish vositasini qayta yuklash miltiq va to'pponcha patronini qayta tiklashga qaraganda ancha murakkab va shuning uchun miltiq va to'pponcha patronlarini qayta yuklash presslariga nisbatan o'q otish pristavkalari juda kam ishlatiladi.

.50 BMG va undan kattaroq kartrijli presslar

.50 BMG va undan kattaroq kartridjlarni qayta yuklash uchun qayta yuklash moslamalari odatda kalibrga xosdir, xuddi o'q otish plyonkalariga o'xshaydi, chunki standart o'lchamdagi miltiq va avtomatlarni qayta yuklash presslari bunday ekzotik qayta yuklash xizmatiga bosilishi mumkin emas. Bunday yirik kartridjlarni qayta yuklash ham ancha murakkab, chunki ma'lum miqdordagi kukun yordamida yukni ishlab chiqishda 5 funt shishaning deyarli hammasi talab qilinishi mumkin va sabablarga ko'ra bitta yuk kukuni bilan yuk ishlab chiqilishi kerak. xavfsizlik.

O'ladi

O'ladi odatda ishning shakliga qarab ikki yoki uch donadan iborat to'plamlarda sotiladi. Uch o'lim to'plami to'g'ridan-to'g'ri holatlar uchun kerak bo'lsa, ikkita o'lchov to'plami torli holatlar uchun ishlatiladi. Ikkala to'plamning birinchi matritsi o'lchamlarni aniqlash va dekaplash operatsiyasini bajaradi, faqat 3 o'lim to'plamidagi ba'zi holatlar bundan mustasno, bu erda dekolman ikkinchi o'lim bilan amalga oshirilishi mumkin. Uch o'lim to'plamidagi o'rta o'lim to'g'ridan-to'g'ri qutilarning og'zini kengaytirish uchun ishlatiladi (va agar bu birinchi o'lim bilan bajarilmasa), ikkita o'lik to'plamda butun bo'yni xuddi shunday kengaytiriladi birinchi o'limdan olinadi. O'rnatilgan o'tirgan joydagi oxirgi o'lik o'qni burishtirishi mumkin. O'q o'tirgandan keyin kuchliroq siqishni qo'llash uchun ko'pincha maxsus siqish matritsalaridan foydalaniladi.^[6] Progressiv presslarda ba'zida kukunni kassaga o'lchash uchun qo'shimcha "o'lik" ishlatiladi (garchi u bu ishni aniq shaklga keltirmasa ham, bu haqiqiy o'lish emas).^[10]

Standart matritsalar ishlab chiqarilgan qattiq po'lat, va katta miqdordagi kuch talab qiladigan o'lchamlarni qayta ishlash uchun kassani moylashni talab qiladi. Vintovkalarning patronlari katta miqdordagi kuch tufayli har bir ishni moylashni talab qiladi, kichikroq ingichka qurolli patronlar esa o'zgaruvchan moylangan va sirlanmagan qutilaridan xalos bo'lishi mumkin. Karbidli o'liklarning halqasi bor volfram karbid, bu asbob po'latidan ancha qiyin va silliqroq, shuning uchun karbid o'limlari soqol talab qilmaydi.^[6]

Zamonaviy qayta yuklanadigan matritsalar odatda 7 / 8-14 (yoki, masalan,) bilan standartlashtirilgan .50 BMG 1-1 / 4 × 12) iplar bilan o'ralgan va barcha keng tarqalgan markalar bilan almashtirilishi mumkin, ammo eski matritsalar boshqa iplardan foydalanishi va pressga xos bo'lishi mumkin.

Shishadagi bo'yin qutilari uchun qoliplar odatda kamida ikkita o'likdan iborat bo'lib, ba'zida uchdan bir qismi siqish uchun qo'shiladi. Bu qo'shimcha operatsiya bo'lib, qurolning jurnali yoki harakatlanish dizayni xavfsiz ishlashi uchun siqilgan o'q-dorilarni talab qilmasa, masalan, o'q otish qurollarini avtomatik yuklash kerak bo'lsa, bu harakatning velosiped o'qi o'qni orqaga qaytarib yuborishi mumkin, natijada zaiflik va bosim kuchayadi .^[11] Siqish, shuningdek, ba'zida o'qlarni tepada harakatlanishiga yo'l qo'ymaslik uchun o'qlarni tezroq yoqib yuborish uchun bosimni kuchayishi va og'ir orqaga qaytariladigan yuklarni olish uchun tezlikni oshirishga tavsiya etiladi.^[12] Shishaning bo'yin qutilariga o'rnatilgan FMJ o'qlari uchun rulonni siqish odatda o'qda kannelure bo'lmasa, siqilish paytida o'q deformatsiyasini oldini olish uchun ishlatilmaydi. To'siqsiz, tekis devor korpuslari esa konusning qisilishini talab qiladi, chunki ular korpusning og'ziga bo'sh joy ajratib turadi; rulonni siqish ushbu patronlarda bo'sh joy oralig'idagi muammolarni keltirib chiqaradi. Qisqartirilgan, kamarlangan yoki tirnoqli patronlar, odatda, kerak bo'lganda rulon bilan siqib qo'yilishi mumkin. Odatda tekis devorli holatlar uchun uchta matritsa beriladi, qisish uchun ixtiyoriy to'rtinchi o'lik bilan. To'g'ridan-to'g'ri devor korpuslari uchun qisqichlar konvertorlar bo'lishi mumkin, ular avtoyuklagichlarda ishlatiladigan romsiz patronlar uchun mos keladi yoki revolverlarda ishlatiladigan plyonkali kartridjlar uchun eng maqbul bo'lgan rulonli qisqichlar bo'lishi mumkin.^[11]

Shuningdek, maxsus o'limlar mavjud. Bump kalıpları, xonani joylashtirishni engillashtirish uchun darboğaz qutisining yelkasini biroz orqaga qaytarish uchun mo'ljallangan. Ular tez-tez bo'yin matkaplari bilan birgalikda ishlatiladi, chunki zarbaning o'zi ishning bo'yinini boshqarmaydi. Tepalik o'ldirish kamerasi bilan nozik o'q otish miltig'iga ega bo'lgan har bir kishi uchun juda foydali vosita bo'lishi mumkin, chunki o'lchov bu bo'shliqni ushbu noyob kameraga o'rnatishga imkon beradi.^[13] Boshqa o'lim - bu "qo'l o'lishi". Qo'l o'limida iplar yo'q va ular nomidan ko'rinib turibdiki - qo'l bilan yoki qo'lda ishlaydigan arbor pressidan foydalaniladi. Eng mashhur kartridjlar uchun qo'l matkaplari mavjud va ularning o'lchamlari to'liq uzunlikdagi o'limga ega bo'lsa-da, ular odatda bo'yin o'lchamlarini o'ldirish sifatida ko'riladi. Bunda bo'yni kattalashtirish uchun bir-birining o'rnini bosuvchi qo'shimchadan foydalaniladi va bu qo'shimchalar 1/1000 dyuymli qadamlar bilan o'rnatiladi, shunda foydalanuvchi ishning bo'ynini o'z xonasiga moslashtirishi yoki o'q ustidagi bo'yin tarangligini yuqori darajada boshqarishi mumkin.^[14]

Qobiq egalari

Ishni ushlab turish uchun, odatda, alohida sotiladigan qobiq egasi kerak, chunki u o'liklarga majburan va tashqariga chiqadi. Qobiq egalarining alohida sotilishining sababi shundaki, ko'plab patronlar bir xil asosiy o'lchamlarga ega va bitta qobiq egasi turli xil holatlarga xizmat ko'rsatishi mumkin. Qobiq egalari ham ixtisoslashgan va odatda faqat ma'lum bir qayta yuklash moslamasiga mos keladi, zamonaviy matritsalar esa standartlashtirilgan va turli xil presslarga mos keladi.^[6] Qo'llarni astarlash vositalarida (masalan, Li Autoprime vositasi) ishlatish uchun matritsalarda ishlatilgandan ko'ra har xil qobiq ushlagichlari talab qilinadi.

Kukun o'lchovidan va og'irlikdan tortib to hajmgacha o'zgartirish jadvalidan boshqa hech narsani ishlatmasdan yuklash mumkin bo'lsa-da, bu yukni sozlashning aniqligini juda cheklaydi va kartridjlarni kassaga tasodifan haddan tashqari yuk uchun yoki maksimal darajada yuk uchun xavfni oshiradi. yuk. Kukun shkalasi bilan sozlanishi kukun o'lchovi ko'rib chiqilayotgan kukun uchun aniqroq sozlanishi mumkin va o'lchov siljib ketmasligiga ishonch hosil qilish uchun yuklarni tekshirishda tekshirish mumkin. Kukunli trikler yordamida zaryad to'g'ridan-to'g'ri shkala bo'yicha o'lchanishi mumkin va bu eng aniq o'lchovni beradi.^[6]

Tarozi shuningdek o'qlar va qutilarni og'irlik bo'yicha saralashga imkon beradi, bu esa izchillikni yanada oshirishi mumkin. O'qlarni og'irlik bo'yicha saralashning foydasi katta, chunki har bir mos keladigan o'qning to'plami yanada izchil ishlaydi. Vaziyatlarni vazn bo'yicha saralash, ishlarni devor qalinligi bo'yicha guruhlash va ichki hajmlari o'xshash holatlarni moslashtirish uchun amalga oshiriladi. Masalan, harbiy holatlar qalinroq bo'ladi, ko'p marotaba qayta tiklangan holatlarda, o'q otish paytida oldinga guruch oqayotgani sababli devorlari ingichka bo'ladi va keyinchalik ishning og'zidan ortiqcha ish hajmi kesiladi.

Ishni pastga urish uchun asrash uchun turli xil qo'shimcha vositalardan foydalanish mumkin yoki alohida asbobdan foydalanish mumkin. Bir bosqichli press yordamida yuklangan holatlar bosqichma-bosqich bajarilganligi sababli, pog'onalar pog'onalar orasida o'zgarib turishi sababli, maqsadga muvofiq astarlama vositasi ("primer" vositasi deb ataladi) - bu tez-tez pog'onali qadamni " bosish pog'onasi, shuningdek, ko'pincha pressga o'rnatilishi va o'rnatilishi kerak bo'lgan modelga qaraganda ancha mustahkam, natijada astar chuqurligi yanada izchil bo'ladi.^[6]

Turli xil kukunlarni qo'shib, kerakli zaryadni aniq aniqlik bilan o'lchash mumkin. Biroq, kukunning ko'p o'lchovlari tez-tez talab qilinadiganligi sababli va kukunlar zichligi biroz farq qilishi mumkinligi sababli, a chang o'lchovi aniq ¹⁄₁₀ don (6,5 mg) maqsadga muvofiqdir.^[6]

O'q tortuvchisi

Ta'sir o'qi tortuvchisi

Har qanday murakkab jarayon singari, qo'lni yuklashda ham xatolarga yo'l qo'yish oson va o'q tortish moslamasi yuk ko'taruvchiga xatolarni demontaj qilishga imkon beradi. Aksariyat tortuvchilar foydalanadilar harakatsizlik o'qni tortib olish uchun va ko'pincha o'xshash shaklga ega bolg'alar. Ishlatilayotganda, kassa "bolg'a" ning narigi chetida bosh bilan pastga qulflanadi va keyin qurilma silkitilib, qattiq yuzaga uriladi. Keskin zarba to'satdan paydo bo'ladi sekinlashtirmoq ish, ammo og'irroq bo'lgan inertsiya massa o'q uni harakatga keltiradi va shu tariqa uni bir nechta zarbalar bilan qutidan tortib oladi, kukun va o'q ajratilganidan keyin tortib oluvchi ichidagi ushlovchi idishga tushib qoladi. Kollet - o'q tortish uchun kalibrli mahkamlagichdan foydalanadigan, tortib oluvchi korpusni pastga qarab tortish uchun ishlatiladigan tortish moslamalari ham mavjud. Kolletning o'q diametri bilan yaxshi mos kelishi juda muhimdir, chunki noto'g'ri o'yin o'qning sezilarli deformatsiyasiga olib kelishi mumkin.

O'q ushlagichlari, shuningdek, shubhali isbotlanganligi yoki keraksiz konfiguratsiyaga ega bo'lgan o'q-dorilarni qismlarga ajratish uchun ishlatiladi, shuning uchun tarkibiy qismlarni qayta ishlatish uchun qutqarish mumkin. Ortiqcha harbiy o'q-dorilar ko'pincha qismlarga, xususan, eski xorijiy harbiy miltiqlarni olish qiyin bo'lgan patronlar uchun tortib olinadi. Harbiy o'q-dorilar, masalan, suvga va qo'pol muomalaga chidamli bo'lishi uchun ko'pincha qattiq muhrlanadi avtomat oziqlantirish mexanizmlari. Bunday holda, o'q va patron o'rtasidagi muhr o'q tortmasining ishlashiga to'sqinlik qilishi mumkin. O'qni o'tiradigan joy bilan qutiga ozgina surish muhrni buzadi va o'qni tortib olishga imkon beradi.^[15]

Astarlar yanada muammoli masala. Agar astar etarlicha chuqur o'tirilmagan bo'lsa, kartrijni (agar yuklangan bo'lsa) tortib olish mumkin va astarni o'tirish vositasi bilan qayta joylashtirish mumkin. Dastlab olib tashlanishi kerak bo'lgan astarlar tez-tez o'chiriladi - yoki tegishli qurolga astarlangan qutini otish yoki singdirish penetratsion yog ', bu astarda suvga chidamli qoplamalarga kirib boradi.

Yuklangan patronlardan tortib olingan komponentlar ehtiyotkorlik bilan qayta ishlatilishi kerak. Buzilgan yoki noto'g'ri o'lchamdagi noma'lum yoki potentsial ifloslangan changlar, ifloslangan primerlar va o'qlar o'q otishda xavfli vaziyatlarni keltirib chiqarishi mumkin.

Case trimmer

Hornady Manual Case Trimmer

Ishlar, xususan, darboğaz holatlari, otish paytida ko'payadi. Ishning qancha cho'zilishi yuk bosimi, kartrij dizayni, kameraning kattaligi, funktsional kartrijning bo'sh joyi (odatda eng muhim omil) va boshqa o'zgaruvchiga bog'liq. Muvaffaqiyatli xususiyatlarga keltirish uchun vaqti-vaqti bilan holatlarni qisqartirish kerak. Qayta yuklash bo'yicha qo'llanmalarning aksariyati ikkala ro'yxat a trim hajmi va a maksimal uzunlik. Uzoq muddatli holatlar noto'g'ri bo'sh joy va mumkin bo'lgan bosim tufayli xavfsizlik xavfini keltirib chiqarishi mumkin.^[6]

Bir nechta turdagi trimmerlar mavjud. Kalıplara asoslangan trimmerlar ochiq tepaga ega va yuklash jarayonida ishni fayl bilan kesishga imkon beradi. Qo'lda ishlaydigan trimmerlar odatda taglikka ega bo'lib, uning uchida qobiq ushlagichi va teskari uchida kesuvchi uchi bor, uni mahkam ushlash uchun qulflash mexanizmi bilan va kichkina torna singari to'sar o'qiga to'g'ri keladi. Odatda qurilma qo'l bilan buriladi, lekin ba'zida ular burg'ulash yoki quvvatli tornavida ishlatishga imkon beradigan qo'shimchalarga ega. Ishlaydigan trimmerlar ham mavjud. Ular, odatda, dvigateldan iborat (ba'zida elektr matkaplari ishlatiladi) va kassani tegishli uzunlikda qirqish uchun ushlab turadigan maxsus matritsalar yoki armatura, motorni kesish ishlarini bajarishga imkon beradi.^[5][16]

Primer cho'ntak vositalari

Astar cho'ntagida qolgan qoldiq yonish qoldiqlarini olib tashlash uchun primer cho'ntakni tozalash vositalari ishlatiladi; ikkala cho'tka dizayni va bitta pichoq dizayni ham keng qo'llaniladi. Nopok astar cho'ntaklari kartrij boshida yoki undan pastda primerlarni o'rnatishga to'sqinlik qilishi mumkin. Astar cho'ntaklaridagi harbiy burmalarni olib tashlash uchun primer cho'ntak reamerlari yoki svagarlardan foydalaniladi.^[17]

Birlamchi primer cho'ntak chuqurligiga erishish uchun primer cho'ntak formasining vositalari ishlatiladi. These are small endmills with a fixed depth-spacing ring attached, and are mounted either in a handle for use as a handtool, or are sometimes mounted in a battery-operated screwdriver. Some commercial cartridges (notably Sellier & Bellot) use large rifle primers that are thinner than the SAAMI standards common in the United States, and will not permit seating a Boxer primer manufactured to U.S. standards; the use of a primer pocket uniformer tool on such brass avoids setting Boxer primers high when reloading, which would be a safety issue. Two sizes of primer pocket uniformer tools exist, the larger one is for large rifle (0.130-inch nominal depth) primer pockets and the smaller one is used for uniforming small rifle/pistol primer pockets.^[18]

Flash hole uniforming tools are used to remove any burrs, which are residual brass remaining from the manufacturing punching operation used in creating flash holes. These tools resemble primer pocket uniformer tools, except being thinner, and commonly include deburring, chamfering, and uniforming functions. The purpose of these tools is to achieve a more equal distribution of flame from the primer to ignite the powder charge, resulting in consistent ignition from case to case.^[19]

Headspace gauges and modified case gauges

Bottleneck rifle cartridges are particularly prone to encounter incipient head separations if they are full-length re-sized and re-trimmed to their maximum permitted case lengths each time they are reloaded. In some such cartridges, such as the .303 inglizlar when used in Enfield rifles, as few as 1 or 2 reloadings can be the limit, before the head of the cartridge will physically separate from the body of the cartridge when fired. The solution to this problem, of avoiding overstretching of the brass case, and thereby avoiding the excessive thinning of the wall thickness of the brass case due to case stretching, is to use what is called a "headspace gauge". Contrary to its name, it does not actually measure a rifle's bo'sh joy. Rather, it measures the distance from the head of the cartridge to the middle of the shoulder of the bottleneck cartridge case. For semi-automatic and automatic rifles, customary practice is to move the midpoint of this shoulder back by no more than 0.005 inches, for reliable operation, when resizing the case. For bolt-action rifles, with their additional camming action, customary practice is to move this shoulder back by only 0.001 to 0.002 inches when resizing the case. In contrast to full-length resizing of bottleneck rifle cartridges, which can rapidly thin out the wall thickness of bottleneck rifle cartridges due to case stretching that occurs each time when fired, partial length re-sizing of the bottleneck case that pushes shoulders back only a few thousandths of an inch will often permit a case to be safely reloaded 5 times or more, even up to 10 times, or more for very light loads.

Similarly, by using modified case gauges, it is possible to measure precisely the distance from a bullet ogiv to the start of rifling in a particular rifle for a given bottleneck cartridge. Maximum accuracy for a rifle is often found to occur for only one particular fixed distance from the start of rifling in a bore to a datum line on a bullet ogive. Measuring the overall cartridge length does not permit setting such fixed distances accurately, as different bullets from different manufacturers will often have a different ogive shape. It is only by measuring from a fixed diameter point on a bullet ogive to the start of a bore's rifling that a proper spacing can be determined to maximize accuracy. A modified case gauge can provide the means by which to achieve an improvement in accuracy with precision handloads.

Such head space gauges and modified case gauges can, respectively, permit greatly increasing the number of times a rifle bottleneck case can be reloaded safely, as well as to improve greatly the accuracy of such handloads. Unlike the situation with using expensive factory ammunition, handloaded match ammunition can be made that is vastly more accurate, and, through reloading, that can be much more affordable than anything that can be purchased, being customized for a particular rifle.

Materials required

.223 Remington guruch

The following materials are needed for handloading ammunition:^[20]

• Ishlar yoki shotshell korpuslar. For shotshells, plastik yoki qog'oz cases can be reloaded, though plastic is more durable. Chelik va alyuminiy cases do not have the correct qualities for reloading, so a guruch case is essential (although nickel-plated brass cases, while not as reformable as plain brass, can also be reloaded)
• Yonilg'i of an appropriate type. Odatda, qurol patronlari (due to shorter bochkalar ) va shotshells (due to heavier projectile weights) use faster burning tutunsiz changlar va miltiq patronlari use slower burning powder. Powder is generally of the "smokeless" type in modern cartridges, although on occasion the older qora kukun more commonly known as "gunpowder" may be used.
• Mermilar, kabi o'qlar uchun miltiqlar va qurol, yoki otilgan va wads uchun ov miltig'i.
• Centerfire astarlar, most commonly a Boxer-type.

Case lubrication may also be needed depending on the dies used. Karbid pistol dies do not require case lubricant. For this reason, they are preferred by many, being inherently less messy in operation. In contrast, all dies for bottleneck cartridges, whether made of high strength steel or carbide, and steel dies for pistol do require the use of a case lubricant to prevent having a case become stuck in a die. (In the event that a case does ever become stuck in a die, there are stuck case remover tools that are available to remove a stuck case from the die, albeit at the loss of the particular case that became stuck.)

Reloading process

Rifle/pistol cartridges

A vibratory ("dry") case Tumbler

The operations performed when handloading cartridges are:^[17]

• Removing any old, expended primers ("de-priming") from previously fired cases.
• Case cleaning (optional, recommended for reused rifle or pistol cases), can be done with an ultrasonic cleaner yoki bilan mass finishing device known as a "case tumbler". Tumblers uses abraziv granulalar sifatida tanilgan tumbling media ga yonib ketgan the cases, and can be either a tebranish type ("dry tumbling") or a water/yuvish vositasi asoslangan aylanadigan type ("wet tumbling"). In either type, a "media separator" is needed to elak out and remove the abrasive media (which can be stone or ceramic granules, fragments of makkajo'xori yoki yong'oq /kokos chig'anoqlar, or small segments of zanglamaydigan po'lat sim often called "pins") when the cleaning is completed. In the "wet" rotary tumbling, a food dehydrator o'xshash convection dryer is sometimes used to eliminate moisture retention that might later interfere with handloading.
• Case inspection (Look for cracks or other defects, and discard visibly imperfect cases. The interior may be inspected by a wire-feeler or feeler gage to detect emerging interior cracks. Bent case mouths mumkin be repaired during resizing.)
• Lubricating the cases (Carbide dies do not require lubrication.)
• Sizing/resizing the case
• Reaming yoki shamcha crimping the primer pocket (reloading military cases only), or frezeleme the primer pocket depth using a primer pocket uniformer tool
• Measuring and trimming the case length (as needed; rarely required with handgun cases)
• Deburring, reaming the case mouth and size case neck (optional, as-needed; trimmed cases need to be deburred); some bench rest shooters also do outside neck turning at this stage, to make the cartridge case have uniform thickness so that the bullet will be released with the most uniformity
• Cleaning the primer pocket (optional; primer pockets will have deposits from combustion) and do flash hole uniforming (optional, generally, only bench rest shooters do this)
• Expanding or chamfering the case mouth (not required with boattail rifle bullets)
• Cleaning the lubricant from the cases
• Seating a new primer (primer pockets often become loose after multiple loadings; a lack of effort being required to seat new primers indicates a loose primer pocket; cases with loose primer pockets are usually discarded, after crushing the case to prevent its reuse)
• Adding a measured amount of powder (this is a critical step, as incorrect powder charges are extremely dangerous, both underweight as well as overweight)
• Seating the bullet in the case for the correct cartridge overall length (OAL) and for aligning bullet cannelure (if present) with case mouth
• Siqish the bullet in place (optional; some may hold the bullet with neck tension alone)
• Final cartridge inspection

When previously fired cases are used, they must be inspected before loading. Cases that are dirty or tarnished are often polished in a tumbler to remove oksidlanish and allow easier inspection of the case. Cleaning in a tumbler will also clean the interior of cases, which is often considered important for handloading high-precision target rounds. Cracked necks, non-reloadable cases (steel, aluminum, or Berdan primed cases), and signs of head separation are all reasons to reject a case. Cases are measured for length, and any that are over the recommended length are trimmed down to the minimum length. Competition shooters will also sort cases by brand and weight to ensure consistency.^[17]

Olib tashlash astar, deb nomlangan echish yoki depriming, is usually done with a die containing a steel pin that punches out the primer from inside the case. Berdan primed cases require a different technique, either a gidravlik ram or a hook that punctures the case and levers it out from the bottom. Military cases often have crimped-in primers, and decapping them leaves a slightly indented ring (most common) or, for some military cartridges, a set of stabbed ridges located on the edge of the primer pocket opening that inhibits or prevents seating a new primer into a decapped case. A reamer or a swage is used to remove both these styles of crimp, whether ring crimps or stab crimps.^[17] The purpose of all such primer crimps is to make military ammunition more reliable under more extreme environmental conditions. Some military cartridges also have sealants placed around primers, in addition to crimps, to provide additional protection against moisture intrusion that could deactivate the primer for any ammunition exposed to water under battlefield conditions. Decapping dies, though, easily overcome the additional resistance of sealed primers, with no significant difficulty beyond that encountered when removing non-sealed primers.

When a cartridge is fired, the internal pressure expands the case to fit the chamber in a process called obturatsiya. To allow ease of chambering the cartridge when it is reloaded, the case is swaged back to size. Competition shooters, using murvat harakati rifles that are capable of camming a tight case into place, often resize only the neck of the cartridge, called neck sizing, as opposed to the normal full length resizing process. Neck sizing is only useful for cartridges to be re-fired in the same firearm, as the brass may be slightly oversized in some dimensions for other chambers, but the precise fit of case to chamber will allow greater consistency and therefore greater potential accuracy. Some believe that neck sizing will permit a larger number of reloads with a given case in contrast to full size resizing, although this is controversial. Yarim avtomatik miltiqlar and rifles with SAAMI minimum chamber dimensions often require a special small base resizing die, that sizes further down the case than normal dies, and allows for more reliable feeding.^[21]

Once the case is sized down, the inside of the neck of the case will actually be slightly smaller than the bullet diameter. To allow the bullet to be seated, the end of the neck is slightly expanded to allow the bullet to start into the case. Boattailed bullets need very little expansion, while unjacketed qo'rg'oshin bullets require more expansion to prevent shaving of lead when the bullet is seated.^[17]

Large Rifle primers

Priming the case is the most dangerous step of the loading process, since the primers are pressure-sensitive. The use of safety glasses or goggles during priming operations can provide valuable protection in the rare event that an accidental detonation takes place. Seating a Boxer primer not only places the primer in the case, it also seats the anvil of the primer down onto the priming compound, in effect arming the primer. A correctly seated primer will sit slightly below the surface of the case. A primer that protrudes from the case may cause a number of problems, including what is known as a slam fire, which is the firing of a case before the action is properly locked when chambering a round. This may either damage the gun, and/or injure the shooter. A protruding primer will also tend to hang when feeding, and the anvil will not be seated correctly so the primer may not fire when hit by the firing pin. Primer pockets may need to be cleaned with a primer pocket brush to remove deposits that prevent the primer from being properly seated. Berdan primers must also be seated carefully, and since the anvil is part of the case, the anvil must be inspected before the primer is seated. For reloading cartridges intended for use in military-surplus firearms, rifles especially, "hard" primers are most commonly used instead of commercial "soft" primers. The use of "hard" primers avoids otashinlar when loading finished cartridges in the military-surplus firearm. Such primers are available to handloaders commercially.^[22]

The quantity of gunpowder is specified by weight, but almost always measured by volume, especially in larger scale operations. A powder scale is needed to determine the correct mass thrown by the powder measure, as loads are specified with a precision of 0.10 don (6.5 mg). One grain is 1/7000 of a pound. Competition shooters will generally throw a slightly underweight charge, and use a powder trickler to add few granulalar of powder at a time to the charge to bring it to the exact weight desired for maximum consistency. Special care is needed when charging large capacity cases with fast burning, low volume powders. In this instance, it is possible to put two charges of powder in a case without overflowing the case, which can lead to dangerously high pressures and a significant chance of bursting the chamber of the firearm. Non-magnum revolver cartridges are the easiest to do this with, as they generally have relatively large cases, and tend to perform well with small charges of fast powders. Some powders meter (measure by volume) better than others due to the shape of each granule. When using volume to meter each charge, it is important to regularly check the charge weight on a scale throughout the process.^[6]

Competition shooters also often sort bullets by weight, often down to 0.10 grain (6.5 mg) increments. The bullet is placed in the case mouth by hand, and then seated with the press. At this point, the expanded case mouth is also sized back down. A crimp can optionally be added, either by the seating die or with a separate die. Taper crimps are used for cases that are held in the chamber by the case mouth, while roll crimps may be used for cases that headspace on a rim or on the cartridge neck. Roll crimps hold the bullet far more securely, and are preferred in situations, such as magnum revolverlar, where recoil velocities are significant. A tight crimp also helps to delay the start of the bullet's motion, which can increase chamber pressures, and help develop full power from slower burning powders (see ichki ballistik ).^[11]

Tinch okeani single stage shotshell reloading press (an inline design), showing the 5 stations standard to shotshell presses.

Unlike the presses used for reloading metallic cartridges, the presses used for reloading shotgun shells have become standardized to contain 5 stations, with the exact configuration of these 5 stations arranged either in a circle or in a straight row. Nonetheless, the operations performed using the industry-standard 5 station shotshell presses when handloading shotshells with birdshot, although slightly different, are very similar as to when reloading metallic cartridges:

• Selecting an appropriate charge bar and powder bushing, or charge bar with shot bushing and powder bushing, or a universal charge bar (if used) for measuring shot and powder, for the shotshell press.
• Verifying that all components are properly selected (hull, primer, powder, wad, and shot). (No substitutions are allowed in components, nor in charge weights of shot and powder. The only substitution allowed is in the brand of shot and the size of the shot (#8, #9, etc. Also, no substitutions are allowed in the shot material itself (whether it is lead shot, hevi-shot, steel shot, etc.), as the malleability of lead shot is noticeably different than steel.)
• Loading shot and powder in press, and verifying that the as-dropped weights are per an established, published, loading recipe using a calibrated scale. (Typically, 5 to 10 trials of shot and powder drops, each, are recommended by shotshell press or universal charge bar user manuals.)
• Adjusting bushings or universal charge bar settings to account for small differences in densities due to lot-to-lot variations in both powder and shot.
• Inspecting each hull. (Examining for cracks or other hull defects, and discarding any visibly imperfect hulls. Also, turning each hull upside down to remove any foreign object debris before depriming.)
• Removing the fired primer and sizing/resizing the brass outer diameter at the base of the hull (Station 1).
• Inserting a primer in the well of the press, and sizing/resizing the inner diameter of the hull while inserting a new primer (Station 2).
• Verifying primer is fully seated, not raised. If primer is not fully seated, re-running operation at Station 2 until primer is fully seated.
• Positioning primed hull (at Station 3), pulling handle down, toggling charge bar to drop measured amount of powder, raising handle, inserting wad, dropping handle again to seat wad, toggling charge bar to drop measured amount of shot, raising handle.
• Pre-crimping of shell (Station 4).
• Final crimping of shell (Station 5).
• Inspecting crimping on shell. If crimp is not fully flat, re-crimping (Station 5).
• Inspecting bottles of shot and powder on the shotshell press, adding more as needed before it runs out.
• Cutting open 4 or 5 shells randomly selected from a large lot of handloaded shells, respectively, and verifying that the as-thrown weights of powder and shot are both within desired tolerances of the published recipe that was followed. (Optional, but recommended.)

The exact details for accomplishing these steps on particular shotshell presses vary depending on the brand of press, although the presence of 5 stations is standard among all modern presses.

The use of safety glasses or goggles while reloading shotshells can provide valuable protection in the rare event that an accidental detonation takes place during priming operations.

The quantities of both gunpowder and shot are specified by weight when loading shotshells, but almost always measured solely by volume. A powder scale is therefore needed to determine the correct mass thrown by the powder measure, and by the shot measure, as powder loads are specified with a precision of 0.10 don (6.5 mg), but are usually thrown with a tolerance of 0.2 to 0.3 grains in most shot shell presses. Similarly, shot payloads in shells are generally held to within a tolerance of plus or minus 3-5 grains. One grain is 1/7000 of a pound.

Shotshell reloading for specialty purposes, such as for buckshot or slugs, or other specialty rounds, is often practiced, but varies significantly from the process steps discussed previously for handloading birdshot shotshells. The primary difference is that large shot cannot be metered in a charge bar, and so must be manually dropped, a ball at a time, in a specific configuration. Likewise, the need for specialty wads or extra wads, in order to achieve the desired stackup distance to achieve a full and proper crimp for a fixed shell length, say 2-3/4", causes the steps to differ slightly when handloading such shells.

Modern shotshells are all uniformly sized for Type 209 primers. However, reloaders should be aware that older shotshells were sometimes primed with a Type 57 or Type 69 primer (now obsolete), meaning that shotgun shell reloading tends to be done only with modern (or recently produced) components. Being essentially "published recipe" dependent, antique shotshell reloading is not widely practiced, being more of a specialty, or niche, activity. Of course, when reloading for very old shotguns, such as those with Damascus barrels, special shotshell recipes that limit pressures to less than 4500 psi are still available, and these "recipes" are reloaded by some shotgunning enthusiasts. Typical shotshell pressures for handloads intended for modern shotguns range from approximately 4700 psi to 10,000 psi.

Brass shotshells are also reloaded, occasionally, but typically these are reloaded using standard rifle/pistol reloading presses with specialty dies, rather than with modern shotshell presses. Rather than plastic wads, traditional felt and paperboard wads are also generally used (both over powder and over shot) when reloading brass shotgun shells. Reloading brass shotshells is not widely practiced.

Shotguns, in general, operate at much lower pressures than pistols and rifles, typically operating at pressures of 10,000 psi, or less, for 12 gauge shells, whereas rifles and pistols routinely are operated at pressures in excess of 35,000 psi, and sometimes upwards of 50,000 psi. The SAAMI maximum permitted pressure limit is only 11,500 psi for 12 gauge 2-3/4 inch shells, so the typical operating pressures for many shotgun shells are only slightly below the maximum permitted pressures allowed for safe ammunition.^[23] Because of this small difference in typical operating vs. maximum industry allowed pressures, and the fact that even small changes in components can cause pressure variances in excess of 4,000 psi, the components used in shotshell reloading must not be varied from published recipes, as the margin of safety relative to operating pressures for shotguns is much lower than for pistols and rifles. This lower operating pressure for shotguns and shells is also the reason why shotgun barrels have noticeably thinner walls than rifle and pistol barrels.

Huquqiy jihatlar

Since many countries heavily restrict the civilian possession of ammunition and ammunition components, including astarlar va tutunsiz kukun, handloading may be explicitly or implicitly illegal in certain countries. Even without specific restrictions on powder and primers, they may be covered under other laws governing portlovchi materiallar.^[24] Handloading may require study and passing an exam to acquire a handloading permit prior to being allowed to handload ammunition in some jurisdictions. This is done to avoid catastrophic accidents caused by lack of knowledge/skill as much as possible, and also allows the government to maintain information on who reloads their own cartridges. The standards organization C.I.P. rules that the products of handloaders that do not comply with the C.I.P. ammunition approval rules for commercial ammunition manufacturers cannot be legally sold in C.I.P. a'zo davlatlar.

Many firearms manufacturers explicitly advise against the use of handloaded ammunition. Generally, this means that the maker's warranty is void and the manufacturer not liable for any damage to the gun or personal injury if handloaded ammunition is used which exceeded established limits for a particular arm. This arises because firearm manufacturers point out that while they have some influence and scope for redress with ammunition manufacturers, they have no such influence over the actions of incompetent or overly ambitious individuals who assemble ammunition.^[25][26][27]

Qo'shma Shtatlar

In the United States, handloading is not only legal and requires no permit, but is also quite popular. Experts point to potential legal liabilities (depending on the jurisdiction) that the shooter may incur if using handloaded ammunition for defense, such as an implied malice on the part of the shooter, as the use of handloaded ammunition may give the impression that "regular bullets weren't deadly enough".^[28] Additionally, forensic reconstruction of a shooting relies on using identical ammunition from the manufacturer, where handloaded ammunition cannot be guaranteed identical to the ammunition used in the shooting, since "the defendant literally manufactured the evidence".^[28] In particular, powder residue patterning is used by law enforcement to validate the distance between the firearm and the person shot using known facts from the manufacturer about powder type, content, and other factors.

Kanada

Handloading is legal in Kanada. The Explosives Act^[29] places limits on the amount of powder (either smokeless or black) that may be stored in a building, on the manner in which it is stored, and on how much powder may be available for use at any time.^[30] The Act is the responsibility of Tabiiy resurslar Kanada.^[31] If the quantity of powder stored for personal use exceeds 75 kg, then a Propellant Magazine Licence (Type P) is required. There is no limit on the number of primers that may be stored for non-commercial use.^[32]

Germaniya

As an example for a European country, handloading in Germany requires a course, terminated in an exam, in handloading and handling of explosive propellants; often, this is offered in combination with a course and exam in tumshug'i bilan yuklash va qora kukun -shooting. The State's Ministry of the Interior conducts the exam. When passed and the reloader can provide a reason for his will to reload ("Bedürfnisprüfung"), he can apply for a permit to a quota of propellant for five years (after which time he has to extend the permit). Every propellant is recorded into the permit. Primers, cartridges, bullets and reloading equipment are available without permit.

As German law gives maximum pressures for every commercial caliber, the handloader is allowed to non-commercially give away his ammunition. He is liable for incorrect loading. His references are data-books by propellant manufacturers (like RWS), bullet manufacturers (like Speer), reloading tool manufacturers (like Lyman) or neutral manufacturers institutions like the DEVA. Firearms manufacturers give guarantee as long as the handloaded ammunition is within the correct parameters.

The relevant rules for non commercial application can be found in §27 of the Explosives Act ("Sprengstoffgesetz").^[33]

In order to investigate gun destruction – material fault or incorrectly loaded ammunition – , and for handloaders to get data for new loads, gun and/or handloaded cartridges can be sent to the DEVA institute (German institute for testing and examining of hunting and sporting guns);^[34] the DEVA returns a pressure diagram and a report whether this load is within legal range for this ammunition.

Janubiy Afrika

Hand loading or reloading is allowed in South Africa as long as you are in possession of a competency certificate to possess a firearm as well as a license to possess such a firearm. Sport shooters load to make the shooting sports more affordable and hunters load to obtain greater accuracy. Powder and primers are strictly controlled by law and can not exceed for 2 kg for powder and 2400 primers. The amount of ammunition you may have in your possession is also limited to 200 rounds per chambering. If you are a registered dedicated sportsman, the quantities are unlimited. Although the powder's quantity is unlimited if you are a dedicated sportsman, storage of excess amounts of powder is dangerous due to the potential of fire occurring from accidental ignition. A manual from a South African powder manufacturer Rheinmetall Denel Munition (previously Somchem) is available for reloaders with adequate information and guidelines.

Atypical handloading

Berdan primers, with their off-center flash holes and lack of self-contained anvil, are more difficult to work with than the easily removed Boxer primers. The primers may be punctured and pried out from the rear, or extracted with gidravlik bosim. Primers must be selected carefully, as there are more sizes of Berdan primers than the standard large and small pistol, large and small rifle of Boxer primers. The case must also be inspected carefully to make sure the anvil has not been damaged, because this could result in a failure to fire.^[15]

Rimfire cartridges (e.g. 22 Long Rifle ) are not generally hand-loaded in modern times, although there are some shooters that unload commercial rimfire cartridges, and use the primed case to make their own loads, or to generate special rimfire wildcat cartridges. These cartridges are highly labor-intensive to produce.^[35] Historically, liquid priming material was available for reloading rimfire ammunition, but the extreme explosive hazard of bulk primer compound and complexity of the process (including "ironing out" the firing pin strike) caused the practice to decline.

Some shooters desiring to reload for obsolete rimfire cartridges alter the firearm in question to function as a centerfire, which allows them to reload. Often it is possible to reform cases from similarly sized ammunition which is in production, and this is the most economical way of obtaining brass for obscure or out of production calibers. Even if custom brass must be manufactured, this is often far less expensive than purchasing rare, out of production ammunition.^[5] Cartridges like the 56-50 Spencer, for example, are not readily obtainable in rimfire form, but can be made from shortened 50-70 cartridges or even purchased in loaded form from specialty dealers.^[36]

An unusual solution to the problem of obtaining ammunition for the very old pinfire cartridges is even available. This solution uses specialized cartridges that use a removable pin and anvil which hold a percussion cap of the type use in caplock firearms. To reload a fired case, the pin is removed, allowing the anvil to slide out; a percussion cap is placed in the anvil, it is re-inserted, and the pin serves to lock the anvil in place, as well as to ignite the percussion cap.

Shotshell reloading is sometimes done for scatter shot loads, consisting of multiple wads separating groups of shot, which are intended for use at short distance hunting of birds. Similarly, shotshell reloading for buck shot loads and non-lethal "bean bag" loads are sometimes handloaded. These types of shotshells are rarely handloaded.^[37]

Accuracy considerations

Several different powder samples

Precision and consistency are key to developing accurate ammunition. Various methods are used to ensure that ammunition components are as consistent as possible. Since the firearm is also a variable in the accuracy equation, careful tuning of the load to a particular firearm can yield significantaccuracy improvements.^[38]

Ishlar

The internal volume of the cartridge case, or case capacity, significantly affects the pressure developed during ignition, which significantly affects the velocity of the bullet. Cases from different manufacturers can vary in wall thickness, and as cases are repeatedly fired and reloaded the brass flows up to the neck and is trimmed off, increasing capacity as well as weakening the case. The first step to ensuring consistent case capacity is sorting the cases by headstamp, so each lot of cases is from the same manufacturer and/or year. A further step would be to then weigh these cases, and sort by case weight.^[38]

The neck of the case is another variable, since this determines how tightly the bullet is held in place during ignition. Inconsistent neck thickness and neck tension will result in variations in pressure during ignition. These variables can be addressed by annealing and thinning the neck, as well as by careful control of the crimping operation.^[38]

Common Rifle Casings

O'qlar

Bullets must be well balanced and consistent in weight, shape, and seating depth to ensure that they correctly engage the rifling, exit the barrel at a consistent velocity, and fly straight. Buying bullets from a high quality source will help ensure quality, but for ultimate accuracy some shooters will measure even the best bullets, and reject all but the most consistent. Measurement of the weight is the easiest, and bullets that are out of round can be detected by rotating the bullet while measuring with a micrometer. There is even a device available that will detect changes in jacket thickness and internal voids in jacketed rifle bullets, though its high cost makes it prohibitively expensive for all but the most dedicated shooters.^[38]

The transition from case to barrel is also very important. If the bullets have to travel a varying distance from the case to the point where they engage the rifling, then this can result in variations in pressure and velocity. The bearing surface of the bullet should ideally be seated as close as possible to the rifling. Since it is bearing surface that matters here, it is important that the bullets have a consistent bearing surface.^[38]

Load tuning

Tuning load to gun can also yield great increases in accuracy, especially for standard, non-accurized miltiqlar. Different rifles, even of the same make and model, will often react to the same ammunition in different ways. The handloader is afforded a wider selection of bullet weights than can readily be found in commercially loaded ammunition, and there are many different powders that can be used for any given cartridge. Trying a range of bullets and a variety of powders will determine what combination of bullet and powder gives the most consistent velocities and accuracies. Careful adjustment of the amount of powder can give the velocity that best fits the natural harmonics of the barrel (see aniqlashtirish va ichki ballistik ). For ultimate accuracy and performance, the handloader also has the option of using a yirtqich mushuk patroni; wildcats are the result of shaping the cartridge and chamber themselves to a specific end, and the results push the envelope of velocity, energy, and accuracy. Most, but not all, reloads perform best when the powder selected fills 95% or more of the case (by volume).^[38]

Xarajatlarni hisobga olish

Those who reload with the primary goal of maximizing accuracy or terminal performance may end up paying more per reloaded round than for commercial ammunition—this is especially true for military calibers which are commonly available as surplus. Maximum performance, however, requires the highest quality components, which are usually the most expensive. Reloaders who reload with the primary goal of saving money on ammunition, however, can make a few tradeoffs to realize significant cost savings with a minimal sacrifice in quality.^[39]

Case life maximization

Digital calipers for measuring case length

Since the case is the single most expensive part of a loaded round, the more times a case can be re-used, the better. Cases that are loaded to a moderate pressure will generally last longer, as they will not be ish qattiqlashdi or flow under pressure as much as cases loaded to higher pressures. Use of moderate pressure loads extends the life of the case significantly, not to mention saving quite a bit of wear and tear on the barrel.^[40] Work hardening can cause cracks to occur in the neck as the hardened brass loses its malleability, and is unable to survive swaging back into shape during the resizing operation. Rifle brass tends to flow towards the neck (this is why rifle brass must be trimmed periodically) and this takes brass away from the rear of the case. Eventually, this will show as a bright ring near the base of the cartridge, just in front of the thick web of brass at the base. If brass is used after this ring appears, it risks a crack, or worse, a complete head separation, which will leave the forward portion of the brass lodged in the chamber of the gun. This generally requires a special stuck case removal tool to extract, so it is very undesirable to have a head separation.^[15]

With bottlenecked cartridge cases, choosing the right sizing die can also be important. Full length sizing of cartridges is often thought to greatly shorten case life by work hardening the full length of the case, which can cause the case neck to split, although some studies show that the number of reloads possible with a case is essentially the same for either full length sizing as for neck sizing only if the issue is one of neck hardening. If the reloaded cartridges are going to be used in the same firearm in which they were previously fired, though, and if that firearm has a bolt action or other action with a strong camming action on closing, then full length resizing may not be needed. A collet neck sizing die can be used to size just the case neck enough to hold the bullet, and leave the rest of the case unsized. The resulting cartridge will chamber into the specific rifle that previously fired it, though the fit might be tight and require more force to chamber than a full length resized case. The use of a neck-sizing die in conjunction with moderate pressure loads may extend the life of the case significantly by minimizing the amount of case that is work hardened or stretched. This is especially true for reloads intended for military rifles with intentionally large chambers such as the Li-Enfild yilda .303 inglizlar. The use of partial length or neck sizing for cartridges used in such large chambers permits effectively switching the headspacing from relying on the rim of a rimmed cartridge to the shoulder of the bottle neck transition instead, increasing the number of times a rimmed military cartridge can be reloaded from once to perhaps 5 or more times, all while avoiding dangerous incipient head separations. One final form of limiting case wear is, unfortunately, limited strictly to benchrest shooters with custom-cut chambers. The chamber of these rifles is cut so that there is just enough room, typically just a few thousandths of an inch, in the neck area. The result of using this type of chamber is that fired rounds don't require any resizing whatsoever once the case is fired. The brass will 'spring back' a bit after firing, and will properly hold a new bullet without further manipulation. Some refer to this as a 'fitted' neck, however it is a function of both the carefully cut precision neck and the case adjusted to fit with very little clearance.^[19]

Work hardening happens to all cases, even low-pressure handgun cases. The sudden increase in pressure upon firing hits the brass like a hammer, changing its crystalline structure and making it more brittle. The neck of the case, if it becomes too brittle, will be incapable of standing the strain of resizing, expanding, crimping, and firing, and will split during loading or firing. Since the case neck remains in tension while holding the bullet in place, aging ammunition may develop split necks in storage. While a neck split during firing is not a significant danger, a split neck will render the case incapable of holding the bullet in place, so the case must be discarded or recycled as a wildcat cartridge of shorter overall length, allowing the split section to be removed. The simplest way to decrease the effects of work hardening is to decrease the pressure in the case. Loading to the minimum power level listed in the reloading manual, instead of the maximum, can significantly increase case life. Slower powders generally also have lower pressure peaks, and may be a good choice.^[41]

Tavlash brass to make it softer and less brittle is fairly easy, but annealing cartridge cases is a more complex matter. Since the base of the case must be hard, it cannot be annealed. What is needed is a form of issiqlik bilan ishlov berish deb nomlangan differential hardening, where heat is carefully applied to part of the case until the desired softness is reached, and then the heat treatment process is halted by rapidly cooling the case.

Qo'rg'oshin chiqindilarining boshqa manbalari, masalan, tiklangan o'qlar, qo'rg'oshin simi niqobi, qo'rg'oshin trubkasi yoki hattoki qo'rg'oshin kislotali akkumulyator plitalar, (batareyaning zamonaviy komponentlari sifatida juda ehtiyot bo'lish kerak, eritilganda, xavfli, hatto o'lik gazlarni ham chiqarib yuborishi mumkin), ma'lum darajada kuch sarflab, shu jumladan qattiqlikni tozalash va o'lchash uchun ishlatilishi mumkin bo'lgan qo'rg'oshinni berishi mumkin.^[44]

To'q otilgan o'qlar, shuningdek, sotib olinadigan eng arzon o'qlardir, ammo odatda ushbu shaklda faqat avtomat o'qlar mavjud. Ba'zi qurol ishlab chiqaruvchilari, masalan, ko'pburchak miltiqdan foydalanadiganlar Glock va H&K, tashlangan o'qlardan foydalanishni rad eting. O'q otishni istagan otishchilar uchun odatdagidek avtomatlashtirilgan ushbu modellar uchun odatda ikkinchi darajali sotuvdan keyingi bochkalar mavjud va barrel narxi odatda bir necha ming turdan keyin o'q-dorilarni tejash bilan qoplanishi mumkin.

Yumshoq qo'rg'oshin o'qlari odatda tezligi 1000 fut / s (300 m / s) yoki undan past bo'lgan qurollarda ishlatiladi, qattiqroq o'qlardan esa puxta tanlab, tezligi 2000 fut / s (600 m /) bo'lgan miltiqlarda foydalanish mumkin. s) yoki biroz ko'proq. To'qilgan snaryadlarning tezligini cheklashning zamonaviy echimi bu snaryadni himoya po'sti bilan qoplash va uni qurol ichida qo'rg'oshin hosil bo'lmaydigan yumshoq qo'rg'oshin qotishmalari yordamida yuqori tezlikka erishish imkonini beradi.^[45] Chegarasi - bu chang gazining harorati va bosimi o'q poydevorini eritishni boshlaydigan nuqtadir va qurolning teshigida eritilgan va qayta qattiqlashgan qo'rg'oshinning ingichka qoplamasini qoldiradi - bu jarayon teshikni olib borish deb ataladi. Qo'rg'oshin o'qlari ham shunga o'xshash to'liq quvvatli magnum avtomatlarida otilishi mumkin 44 Magnum yupqa alyuminiy bo'lgan gaz chekini qo'shib, rux yoki mis mos keladigan o'qlar asosida mayda tovoning ustiga o'ralgan yuvuvchi yoki stakan. Bu o'q poydevorini himoya qilishni ta'minlaydi va qurolning o'qi 1500 fut / s dan (450 m / s) yuqori, o'qning etakchisi kam yoki umuman yo'q.^[44][46]

Gazni tekshirishda ishlatish uchun mo'ljallangan bunday quyma qo'rg'oshin o'qlari quyma qo'rg'oshin o'qining orqa qismida pasaytirilgan diametrga ega bo'ladi, uning ustiga gaz chekini moylash / o'lchamlarini o'zgartirish uchun press yordamida almashtirish mumkin. Bochkaning miltiqlanishiga yo'l qo'ymaslik uchun barcha quyma qo'rg'oshin o'qlari, gaz tekshiruvi bilan yoki bo'lmasdan, hali ham moylanishi kerak. Maxsus maqsadli o'qni qayta ishlash moslamasi bo'lgan moylash / o'lchamlarini o'zgartirish pressi, o'qlarni moylash va o'lchamlarini o'zgartirishga bag'ishlangan avtonom press bo'lishi mumkin yoki qo'l yuklagich ixtiyori bilan qayta yuklash pressiga qo'shimcha bo'lishi mumkin. Hamma qo'l ko'taruvchilar qo'rg'oshin o'qlarining o'lchamlarini o'zgartira olmaydilar, ammo barcha yuk ko'taruvchilar quyma qo'rg'oshin o'qlarini moylashadi. Soqol bosish vositasidan foydalanishning bir usuli shunchaki o'qlarni o'q bilan qoplashdir, uni purkagich bilan, stakan ichida, suyuq ichak bilan plastik ichakda, eritilgan o'q patnisida yoki hatto qo'lda moylash jarayoni.

Ov miltig'ining snaryadlari uchun qurbongohlar, shuningdek, ov qurollari tomonidan toza o'q qo'rg'oshinidan otilib chiqiladi, keyinchalik ularni o'q otish qurollariga qaytarish uchun. O'qotar qurol qutilaridagi rulonli qisqichlar odatda ushbu quyma qo'rg'oshin shlyuzlarini qo'lda yuklash uchun ishlatilgan bo'lsa-da, o'qotar qurolga o'qni qayta yuklashda ishlatiladigan burma burmalar o'rniga, ba'zi nashr etilgan retseptlarda, ayniqsa, burma burmalar mavjud. Sabot sifatida ishlatiladigan burmali kıvrımlar va otishni o'rganish vositalaridan foydalangan holda nashr etilgan retseptlar uchun, sluglarni hech qanday rulonli siqish vositalarini talab qilmasdan, standart tortishish mashinalari va texnikasi yordamida osongina qayta tiklash mumkin. Dumaloq kıvrımlar yoki katlamalı kıvrımlar ishlatiladimi, qo'rg'oshin shlangi odatda miltiq ovlashga taqiqlangan yurisdiktsiyalarda ishlatiladi, chunki otilgan shlaklar sayohat qilmaydi, ammo qisqa masofalarga, o'q otish paytida bir necha milya masofani bosib o'tishi mumkin. . Qo'rg'oshin shilimshiqlaridan foydalanish aholi punktlari yaqinida katta ovni ovlashda juda keng tarqalgan.

Xuddi shu tarzda, quyma qo'rg'oshinli baktshot ko'pincha ov hayvonlari uchun ov miltig'ining po'stlog'iga qayta yuklash uchun qo'l yuklagichlar tomonidan tashlanadi. Keyin o'qni o'qi o'qi o'qi qobig'iga joylashtirilishi kerak, chunki o'q otilgan o'q po'stlog'ining o'lchovi, vadning tanlanishi, kukun hajmi va kattaligiga qarab aniq konfiguratsiyalarda to'pponcha to'plarini to'plash kerak. bukshotdan (masalan, 00, 000, 0000 bakshot). Bunday quyma qo'rg'oshinli baktsot hech qachon o'qni o'qqa tutadigan press zaryad satridan qayta yuklanayotganda ov miltig'ining qobig'iga tushirilmaydi.

Swaging

Aksariyat o'q otuvchilar, ayniqsa miltiq va to'pponchalarda jaketli o'qlarni afzal ko'rishadi. Qattiq ko'ylagi materiali, odatda mis yoki guruch, deformatsiyaga qarshi turadi va qo'rg'oshindan ancha yuqori bosim va haroratni boshqaradi. Bir nechta kompaniyalar taklif qilishadi chayqalish tijorat ko'ylagi o'qlari bilan raqobatlashishi yoki undan ustun turishi mumkin bo'lgan kichik hajmdagi ko'ylagi o'qlarini ishlab chiqaradigan presslar (qo'lda ham, gidravlikada ham). Ikkita almashtirish uskunalari ishlab chiqaruvchilari burilish uchun mo'ljallangan uskunalar va o'liklarni taklif qilishadi 22 uzun miltiq 22 kalibrli (5,56 mm) o'q uchun guruch kurtkalaridagi holatlar.^[44][47] O'qni almashtirish uchun qo'llanma tomonidan taqdim etilgan Korbin.

Swage Corbindan vafot etadi, masalan, uchta variantda keltirilgan:

• Qayta yuklash moslamasida o'qni almashtirish uchun R o'limidan foydalaniladi. Hech qanday qimmat maxsus press kerak emas; shu bilan birga, qayta yuklovchi matbuot o'qlarning barcha kalibrlari va variantlarini o'zgartira olmaydi.
• S matritsalar qo'lda presslash uchun po'lat matritsalardir. Ularning maksimal kalibri .458 dyuym (11,6 mm) va ko'ylagi maksimal uzunligi 1,3 dyuym (33 mm).
• H o'limlari uchun mo'ljallangan o'limlardir gidravlik presslar va 25 millimetrgacha bo'lgan kalibrlarda (0,98 dyuym) va ko'ylagi uzunligi 1,3 "dan yuqori. Shlangi pressda o'qlar chang metall almashtirish mumkin.

Har bir o'q diametri va o'q turlarining aksariyati maxsus o'liklarga muhtoj, bu esa mablag 'sarflashni talab qiladigan korxonaga aylanadi.

Sotib olingan o'qlar

Avtoulovchilar swage qilish imkoniyatini tanlashadi, ammo ko'pchilik shvedning noaniq tabiati va ixtisoslashgan, qimmatbaho uskunalar tufayli oldindan tayyorlangan ko'ylagi o'qlarini sotib olishni tanlashadi. Ko'ylagi o'qini ishlab chiqarish jarayoni quyma o'qqa qaraganda ancha murakkab; birinchi navbatda, ko'ylagi aniq qalinlikdagi metall varaqdan teshilib, oldindan o'lchangan qo'rg'oshin yadrosi bilan to'ldirilgan bo'lishi kerak va keyin bir necha qadamda yuqori bosimli press yordamida shaklga o'tkazilishi kerak. Ushbu jarayon jaketli o'qlarni o'rtacha tashlangan o'qlarga qaraganda ancha qimmat qiladi. Buni yanada murakkablashtiradigan, boshqariladigan kengaytiruvchi o'qlarga talablar (qarang terminal ballistikasi ), bu ko'ylagi va yadro o'rtasida qattiq bog'lanishni talab qiladi. Premium kengaytiruvchi o'qlar, mos keladigan darajadagi o'qlar, eng yuqori darajadagi xarajatdir.

Qoplangan o'qlar

1980-yillarda qo'lda yuk ko'taruvchiga tejamkor alternativa mis bilan ishlangan o'q mavjud edi.^[48] Mis bilan qoplangan o'qlar - bu qo'rg'oshin o'qlari elektrokaplangan mis ko'ylagi bilan. Qoplangan ko'ylagi yupqa bo'lsa-da, qoplama ko'ylagi oddiy elektroplastdan ancha qalinroq bo'lib, o'qning strukturaviy yaxlitligini ta'minlaydi. Ko'ylagi mustahkamlikni ta'minlaganligi sababli, yumshoq qo'rg'oshin ishlatilishi mumkin, bu esa o'qlarni burish yoki qoplashdan oldin shaklga tashlashga imkon beradi. Ko'pchilik miltiq patronlari uchun etarlicha kuchli bo'lmasa-da, plita o'qlari ko'plab qurol tabancalarida yaxshi ishlaydi va tavsiya etilgan maksimal tezlik 1250 fut / s (375 m / s) ni tashkil qiladi.^[49] Qoplangan o'qlar narxlari bo'yicha quyma va an'anaviy ko'ylagi o'qlari orasida tushadi.

Dastlab faqat qo'l yuk ko'taruvchilarga kamzulli o'qlarning arzon o'rnini bosuvchi vosita sifatida sotilgan bo'lsa-da, qoplama o'qi uzoqqa cho'zilgan. O'q-dorilar ishlab chiqaruvchisi Tezroq endi mis qoplamali tijorat maqsadlarida ishlatiladigan qurol-yaroqli "Oltin nuqta" liniyasini taqdim etadi ichi bo'sh o'qlar.^[50][51] Elektrokaplama jarayoni natijasida hosil bo'lgan ko'ylagi va yadro o'rtasidagi kuchli bog'lanish kengayib borayotgan o'qlarni bir-biriga juda yaxshi bog'lab turadi va "Oltin nuqta" liniyasi hozirda ko'plab politsiya bo'limlarida foydalanilmoqda.^[52]
