Hunters and shooters from Michigan to Mississippi are asking, what’s the difference between 360 Buckhammer and 450 Bushmaster?

If you’re in the market for a new deer cartridge or rifle this hunting season, read on to get details on these two straight wall ammo stalwarts.

What is 360 Buckhammer?

Legal to hunt with nationwide, 360 Buckhammer is a modern, rimmed, straight wall cartridge optimized for lever action rifles and revolvers. With a 1:12 twist rate and muzzle velocities between 2,200 FPS and 2,400 FPS, 360 Buckhammer is a faster version of the 30-30 Winchester –– accurate and deadly to 200 yards and further.

This new cartridge gives shooters the ability to run brush-busting .358 diameter bullets either supersonic or subsonic. Remington offers 180gr and 200gr Core-Lokt ammo in 360 Buckhammer, with more options coming soon.

Buckhammer’s shootability, accuracy and velocity provide advantages over similar cartridges in its class – like 350 Legend or 30-30 Winchester – without the heavy recoil like 45-70 Gov. or 450 Bushmaster. This has made BHMR a popular choice among deer hunters.

Designed in 2007, 450 Bushmaster is a straight wall cartridge with a rebated rim that is usually chambered in semi-automatic AR-10/MSR rifles or bolt action rifles, as well as some big-bore handguns.

Available in a variety of barrel twist rates to stabilize .452 diameter 185 to 300 grain bullets, Bushmaster loads have a muzzle velocity of about 1,900 FPS – 2,200 FPS depending on your platform, propellant, and choice of bullet.
