.450 Bushmaster

The straight-wall sledgehammer — decisive on deer and hogs inside 200 yards, with recoil and trajectory that both remind you it's a big pistol bullet moving fast.

Origin

Tim LeGendre concept, Bushmaster and Hornady, USA

History

Inspired by Jeff Cooper's 'Thumper' concept of a big-bore AR, Tim LeGendre's .45 Professional was licensed to Bushmaster and standardized with Hornady around 2007 as the .450 Bushmaster. It idled along until Midwestern straight-wall deer regulations made it a star, offering serious close-range power from ARs and bolt guns alike. It anchors the heavy end of the straight-wall category.
