DEVELOPMENT OF CASE, CARTRIDGE, ALUMINUM, FAT49E4

Abstract

The 7.62mm aluminum cartridge case was designed, developed, and evaluated. Initial development utilized regular brass cartridge case tooling with minor changes. Modifications to the initial cartridge case design eliminated problems encountered during fabrication. Various firing casualties such as primer leaks, blown primers and gas-eroded heads were encountered during testing in rifles and machine guns. Changes in heat treatment, the type of propellant, and primer used and a closer control of the head area dimensions of the case resulted in the fabrication of a 7.62mm aluminum cartridge case that is almost completely free of defects.
