Cartridge Case Manufacture

Home > Small Arms Ammunition > Cartridge Case Manufacture

Cartridge cases fall into two broad categories—metallic and shotshell. Metallic cartridges are used in rifles and handguns and are comprised completely of metal. Shotshell cases are most often hybrids, combining a small amount of metal with paper or plastic.

Metallic Cases

Metallic case production is similar to bullet jacket production, except that the raw material is brass (copper: zinc ratio of 70:30). In brass mills, the standard name for this alloy is cartridge brass. Rimfire and centerfire cases require different processing.
