50 Beowulf ammo (or 12.7x42 ammo) is a specialized cartridge designed for AR-platform rifles. It's a low velocity, heavy-hitting round optimized for high stopping power at close to medium ranges. The Beowulf bullet is nearly twice the diameter of the similar 6.5mm Grendel, and the parent cartridge is the .50 Action Express, allowing .50 Beowulf ammo to have bullet weights of 300 to 400 grains, perfect for use at military checkpoints where penetrating windshields and body panels of vehicles requires more than the standard 5.56mm NATO round. Although designed and marketed as a tactical military and police cartridge, 50 Beowulf rounds are gaining in popularity as a North American hunting cartridge for close to mid-range hunting of deer, black bear, and even moose.
