  • Betley magnum cartridge system
    Patent number: 11181348
    Abstract: The present disclosure provides a cartridge that modifies the .223 cases to achieve a cartridge length of 38.3 mm for use with a bullet (e.g., 110 g). The present cartridge system allows the use of a 30-caliber bullet to be used in an AR15 rifle/pistol platform. The decreased cartridge length optimizes the powder burn rate and pressure, which in turn has a greater effect on the ballistics of the round. The present system yields 300-400 ft/s higher velocity over the .300 Blackout in rifle length barrels and greater than 500 ft/s in shorter pistol barrels.
