Evaluation of 7.62 MM Cartridges Assembled with Caliber .30 API and Incendiary Bullets
Abstract:
This report describes an evaluation of a sample of 7.62 mm cartridges that were assembled with Caliber .30 armor piercing incendiary API and incendiary bullets for the U.S. Air Force USAF. The terminal performance as well as the overall cartridge performance was evaluated. The results are presented in this report. In general, the 7.62 mm cartridges, assembled with Caliber .30 API and incendiary bullets, performed satisfactorily in the 7.62 mm minigun. However, the rifling twist of other 7.62 mm weapons is slower than that in the minigun and did not provide adequate spin to stabilize the bullets. The terminal performance of these cartridges is similar to that of their Caliber .30 equivalents. It was concluded that the 7.62 mm API and incendiary cartridges described in ths report are suitable for minigun use.
