The .375 Raptor is a powerful .375 caliber cartridge designed for the AR-10 platform, offering exceptional performance for hunting and tactical applications. Developed by North American Sportsman, it is based on a .308 Winchester case, necked up to accept .375-caliber bullets.
This cartridge delivers superior energy and penetration, making it ideal for big game hunting, including elk, moose, and even dangerous game. It supports subsonic and supersonic loads, with bullet weights ranging from 180 to 350 grains. The .375 Raptor maintains reliable feeding in semi-automatic rifles while providing increased stopping power over the .308 Winchester.
