The 450 Bushmaster ammo is descended from the Thumper concept popularized by the gun writer Jeff Cooper.

Cooper was dissatisfied with the small-diameter 5.56×45mm NATO (.223 Remington) of the AR-15, and envisioned

a need for a large bore (.44 cal or greater) cartridge in a semi-automatic rifle to provide one-shot kills on big-game

animals at 250 yards. Inspired by this, LeGendre developed his .45 Professional cartridge, and later

built and delivered an AR-15 in .45 Professional to Cooper. 450 Bushmaster Ammo,

Bushmaster requested the ammunition manufacturer Hornady to produce the

.45 Professional cartridge for this project, but Hornady wanted to shorten the cartridge case

and overall length to accommodate their 0.452 in. 250-grain pointed SST flex-tip bullet. Bushmaster

and LeGendre approved the change from a 1.772 in. (45 mm) case and 2.362 in. (60 mm) OAL to the

now standard 1.700 in. (43.18 mm) case and 2.260 in. (57.40 mm) OAL. This permitted operation in

the more abundant and popular AR-15 platform versus the AR-10 platform. Also, a name

change to “.450 Bushmaster” was approved.

With such a large caliber bullet, 450 Bushmaster ammo is a big-game hunting round designed

for the AR-15, a rifle that is traditionally chambered for the small caliber high velocity 223/5.56 cartridge.

The 450 Bushmaster round was named after the bullet’s size and the rifle brand that originally chambered it.
