450 Bushmaster

We understand the importance of offering reliable and high-quality ammunition to our customers, which is why we are proud to provide 450 Bushmaster Ammo for sale. The 450 Bushmaster is a rifle cartridge developed by Tim LeGendre of LeMag Firearms and licensed to Bushmaster Firearms International. It is designed to be used in standard M16s and AR-15s, utilizing modified magazines and upper receiver assemblies.


The history of the 450 Bushmaster can be traced back to the Thumper concept introduced by gun writer Jeff Cooper. Cooper recognized the limitations of the small-diameter 5.56x45mm NATO (.223 Remington) cartridge used in the AR-15 and envisioned the need for a larger bore cartridge (.44 caliber or greater) capable of delivering one-shot kills on big-game animals at distances of up to 250 yards. Inspired by this concept, LeGendre developed the .45 Professional cartridge, eventually delivering an AR-15 chambered in .45 Professional to Cooper.


The 450 Bushmaster utilizes .452-inch bullets due to lower impact velocities and energies that would not adequately expand heavier jacketed .458-inch bullets. It is chambered in bolt-action rifles by Ruger, Savage, Mossberg, and Remington, as well as Ruger’s No. 1 single-shot rifle and AR-15 rifles, including AR-15 pistols.
