COMBUSTIBLE AMMUNITION FOR SMALL ARMS. 2. DEVELOPMENT OF A COMBUSTIBLE SMALL ARMS CARTRIDGE
Abstract
Combustible 7.62 mm ammunition, consisting of a molded integral propellant charge and a dual primer, was developed. When fired in a self-obturating 7.62 mm test weapon over the temperature range -65 to 160 deg F, this cartridge yielded mean ballistic performance similar to that obtained with the standard M59 metal cased cartridge. Velocity reproducibility, however, was poorer than that obtain d with the standard cartridge. Accuracy was slightly less with the combustible ammunition. The combustible dual primer, which consisted of a percussion sensitive cap and a pellet of standard styphnate primer mixture, provided adequate and reproducible ignition. Molded charges had a considerable degree of inherent moisture resistance. Water immersion tests revealed no substantial changes in velocity or pressure after ten months exposure. Firings were conducted with molded charges coated with various materials to determine the degree of consumption of the coatings. All coatings were consumed.
