Nicknamed “Thumper,” the .450 Bushmaster was designed as a close range, big bore hunting caliber for the AR-15 platform. As with most AR cartridge conversions, making the change to .450 Bushmaster only requires swapping out the upper receiver.

With the introduction of new bolt action rifles in this caliber and many states changing game laws to allow straightwall cartridges for deer hunting, the .450 Bushmaster is enjoying a surge in popularity.

Ruger now offers their American Ranch and Gunsite Scout bolt action rifles chambered in the .450 Bushmaster caliber. This cartridge utilizes the common .452-inch diameter bullet. Reloaders can use bullet weights anywhere from 160-350+ grains.
