History of the 450 Bushmaster

The impetus for the .450 Bushmaster was actually a call-to-arms, so to speak, for a more effective, one-shot-and-done defense cartridge. The late and often controversial Col. Jeff Cooper—champion of big-bore knockdown power in both rifles and handguns—had long held that the U.S. military’s adoption of the 5.56 NATO cartridge was a mistake. He argued (as did many frontline soldiers) that the diminutive round was insufficient for getting the job done quickly in battle conditions. Cooper, always a fan of the .45 ACP pistol cartridge, envisioned a similar-sized pill designed for a carbine—something that would put the bad guy down with decisive, one-shot finality. Being a hunter as well as a tactical trainer and theorist, Cooper also acknowledged the benefits of such a round for big-game applications. Not cape buffalo or brown bear, perhaps, but certainly a score-settler for any of North America’s Cervidae family as well as hogs and black bear.
