DEVELOPMENT OF A 7.62MM WROUGHT ZINC ALLOY BLANK CARTRIDGE FOR USE IN THE M-14 RIFLE AND M-60 MACHINE GUN.

Abstract

Work under the contract has shown that a blank cartridge can be produced from wrought zinc alloy which will function only in the M-14 rifle. Since the case does not have a bullet simulating extension it will not feed in the M-60 machine gun. Addition of a bullet simulating profile to the case causes neck and body splits to occur at low temperature firing. Investigation of various manufacturing variables has been unsuccessful in eliminating neck and body splits with this type case. Variations in raw material are considered to be the primary cause of varied good and bad results. A thorough investigation of raw material variables, not conducted under this contract, is a logical next step. Cartridges produced were manufactured on the type of equipment currently in use for the production of 7.62mm NATO ammunition. (Author)
