Abstract:

The U.S. Army Research Laboratory ARL conducted a study to examine the effects of varying a small caliber 7.62 mm cartridge s spit-hole on the interior and exterior ballistic performance of the cartridge. Along with standard Boxer primers, a Berdan style primer configuration is evaluated. Performance metrics evaluated were cartridge pressure, primer pocket pressure, and muzzle velocity.
