Abstract:
1. A system for preventing the discharge of a live ammunition cartridge having an angled shoulder and creating pressure when fired and including a bullet portion normally propelled by said pressure from a rifle or machine gun having a barrel with a longitudinal axis within which the ammunition cartridge is loaded and two sides, comprising: the barrel of the rifle or machine gun having at least two apertures formed therein, with each of said at least two apertures being aligned with the shoulder of said live ammunition cartridge and said longitudinal axis of said barrel; and said live ammunition cartridge and said barrel being cooperatively associated, so as to vent said pressure created by firing said ammunition cartridge through said barrel apertures and thereby deprive said live ammunition cartridge of sufficient pressure to propel said bullet along said longitudinal axis of said barrel and retaining said bullet in said barrel.
