Bullet Diameter: .452”
Uses: Hogs, Bears, Deer, Elk, Bison and Moose (with appropriate loads)
Effective Range: 0-300 yds.
Advantages: Hits hard for use on large game. Satisfies the straight wall cartridge requirements in multiple states allowing for use in areas not previously open to rifle hunting.
History: As with most cartridges, the 450 BM was around as a wildcat long before it was officially adopted by SAAMI in 2008. The result of a joint project between Bushmaster and Hornady.
