The concept for the .450 Bushmaster was developed by the late Col. Jeff Cooper. He recognized that a big bullet is a good thing when shooting big game. He thought that the perfect rifle for most “general” big-game hunting would be a semi-automatic variant, larger than .44-caliber and capable of taking big game out to 250 yards. He called this the “Thumper” concept.

Tim LeGendre, of LeMag Firearms, developed the cartridge and named it the .45 Professional. He licensed the rights to Bushmaster Firearms International (BFI). Hornady worked in conjunction with Bushmaster and developed the ammo. The company modified the case a little so it would work better with Hornady’s proven SST Flextip bullet. With LeGendre’s permission, the name was then changed to .450 Bushmaster, and the cartridge was introduced in 2007.

Of course, bigger cartridges lower magazine capacity compared to 5.56 NATO, but the magazines will hold more ammo than a bolt-action and reloads will be much faster. You also will have a lot of fight-stopping power with each of these bullets. We have never seen a complaint in the history books about the lack of stopping power from the .45-70 Gov’t used by the military in the 1800s. There are, on the other hand, a lot of complaints about the stopping power of our current 5.56 NATO cartridge and yes, despite what you read on the Internet, “stopping power” is a real thing. Don’t let anybody tell you that size doesn’t matter in a fight or when hunting. It does. Big bullets make bigger holes, smash more structure and rip up a lot more vital stuff than little bullets.
