Abstract

Bullets and rounds of ammunition that are configured for use with small-caliber semi-automatic and automatic weapons. These small-caliber bullets and rounds of ammunition provide subsonic flight when discharged in a semi-automatic or fully-automatic weapon. These small-caliber bullets and rounds of ammunition also provide sufficient barrel bore pressure characteristics for cycling a gas-energized bolt actuation mechanism of such semi-automatic or fully-automatic weapon without the use of a sound suppressor to augment gas pressure within the barrel bore of the weapon.
