450 Bushmaster (The Thumper)
,
Current Pistol & Rifle Cartridge
.
Introduced in 2007 by Bushmaster & Hornady:  the New 450 Bushmaster (nicknamed the Thumper) is the most radical
cartridge ever chambered in production AR-15 pistol & rifle type firearms.
Hornady took big bore performance to the most popular semi-automatic rifle in America - opening a whole new world of hunting
to the battle-proven AR-15 platform.
Hornady engineers worked closely with the Bushmaster design team building the cartridge to 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! Note the rebated rim ,which is less diameter then the case, on the case, so the
cartridge can be used in a AR-15 with the correct barrel and clips.
