A headstamp is the markings on the bottom of a cartridge case designed for a firearm. It usually tells who manufactured the case. If it is a civilian case it often also tells the caliber: if it is military, the year of manufacture is often added. The headstamp is punched into the base of the cartridge during manufacture. A resource for identifying where the ammunition originated can be found at (Cartridge Collectors ). ==Australia== * BB (1986–Present) - ''Bertram Bullet Co. Pty. Ltd.'' Seymour, Melbourne, Victoria. Bruce Bertram bought Super Cartridge Co.'s machinery and moved it to Seymour, where he began manufacturing brass cases for handloaders. Brass is sold in lots of 20-case cartons and can be made to customer's specifications with personalized headstamps. * ICI-ANZ - ''Imperial Chemical Industries - Australia / New Zealand'' Deer Park, Melbourne, Victoria. Manufactured cartridges and shotshells from the 1940s until the late 1970s. They also made brass cases for filling and loading by their parent company in the United Kingdom and produced Australian-gauge shotshells for the local market. * RBA or RIVERBRAND (1945? - early 1980s) - ''Riverbrand Ammunition Company'', Hendon, South Australia, Australia.〔(RIVERBRAND )〕 Syd Churches, owner of the Taipan Bullet Company, bought out the defunct Small Arms Ammunition Factories No. 3 & 4 at Hendon after the war. Initial production just remanufactured old military-surplus brass cases with new RWS-made non-corrosive Berdan primers and mated them with Taipan-manufactured bullets to make cheap .303 Imperial and 7.62mm NATO ammo. Early new production (marked "RBA") used Berdan primed brass cases. Full production (marked "RIVERBRAND") used newly manufactured Boxer-primed cases in a variety of service pistol and "wildcat" sporting rifle cartridges, as well as new brass for handloaders. They also made ammo for Sportco in Adelaide under the SPORTCO headstamp. Riverbrand was always a small-scale endeavor, as there was too much competition from Super Cartridge Company (their only domestic manufacturing rival) and foreign ammunition manufacturers. After Churches' death in the late 1970s, RIVERBRAND's bullet-making machinery was sold and moved to Gympie, Wide Bay–Burnett, Queensland, where it was set up as TAIPAN Bullets.〔(TAIPAN Bullets )〕 Owner Malcolm Bone now manufactures bullets in small lots for handloaders, since the company's major toolmaker and die-setter died a few years ago.〔 * SUPER (? - 1985) - ''Super Cartridge Co.'' Manufacturer of cartridges, shotshells, and bullets and brass cases for handloading. They originally sold sporting cartridges made from reloaded Australian-made .303 Imperial brass and sold "wildcat" cartridges made from the base .303 cartridge. (These usually had the original Small Arms Ammunition Factory headstamp on them). They also made proprietary "wildcat" ammunition for the MYRA Sports Store in Broken Hill. They were sued for copyright infringement in the early 1980s by Olin-Winchester for their similar one-piece polymer shotshell design. They were barred from making the shells, gave up manufacturing shotshells altogether, and later went out of business in the mid-1980s. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Headstamp」の詳細全文を読む スポンサード リンク
