The .450 Bushmaster cartridge fires a .452 inch diameter bullet at a velocity of around 2,200 feet per second. This results in a large amount of energy being delivered to the target, which can make it an effective cartridge for hunting, particularly in states where straight-walled cartridges are legal for hunting. It is also being used by some law enforcement agencies as a close-range tactical cartridge.
