Heavy rifle A-Frame bullets are for use on dangerous game. The bullet initiates expansion at 1650 feet per second on the low end and stays together at 3000+ feet per second on the high end. Controlled expansion of 2x its original caliber and 95%+ weight retention make the A-FrameA(R) bullet superior in downrange energy and stopping power. Terminal performance is unequaled.
