ABSTRACT:
Ammunition having increased projectile velocity and energy without increasing the chamber pressure within a firearm such as a handgun, rifle, anti-aircraft gun, canon, etc. This is accomplished by simultaneously incorporating at least two of three interdependent modifications. The concept consists of using a specific gunpowder pseudo overcharge by adding more and/or faster burning explosive, in conjunction with a projectile having an internally jacketed axial bore. The jacketed bore must possess sufficient area to prevent the pseudo overcharge pressure from exceeding the predetermined pressure specification. The net result is a pressure and confident modification of the gunpowder burning parameters which produce much higher average propulsion pressure for any given peak pressure.
