Description

Nicknamed “The Thumper,” the 450 Bushmaster is the most radical cartridge ever chambered in production AR-15 type firearms. Hornady brings big bore performance to the most popular semi-automatic rifle in America — opening a whole new world of hunting to the battle-proven platform.

Hornady engineers worked closely with the Bushmaster design team building the cartridge to wring every last ounce of performance from the AR-15 without sacrificing any strength or reliability.

Well suited to hunt any North American game, the 450 Bushmaster will quickly become a favorite of bear country guides. By simply switching uppers, shooters can go from the prairie dog towns of South Dakota to bear country in the north woods!

• The 450 Bushmaster fires Hornady’s 0.452” 250 gr. SST-ML featuring Hornady’s Flex Tip™ technology.
• The overall cartridge matches the 223 Remington at 2.250”, but uses a specially designed magazine.
• The SST’s sleek profile makes for surprisingly flat trajectories and tremendous downrange energy.

Put it all together, and you have a cartridge that gives your AR series rifle a serious attitude adjustment!
