Overview of 450 Bushmaster Ammo
450 Bushmaster is a big-bore, straight-walled hunting cartridge designed to fit the AR-15. It fires a .452-inch bullet, usually 250 to 300 grains, at around 2,000 to 2,200 fps. That delivers heavy-hitting performance on deer, hogs, and black bear out to about 200 to 250 yards, with recoil similar to a 12 gauge slug.
Its straight-walled case makes 450 Bushmaster legal for deer hunting in several states that restrict rifle cartridges, including parts of Michigan, Ohio, Indiana, and Iowa. Rules vary and change, so always check your state's current regulations. For another straight-wall option, see our 350 Legend ammo.

Frequently Asked Questions
What do I need to shoot 450 Bushmaster in an AR-15?
You keep your AR-15 lower receiver and add a 450 Bushmaster upper with its own barrel and bolt. 450 Bushmaster also needs dedicated magazines, which are typically single-stack and hold fewer rounds than standard AR-15 magazines.
Is 450 Bushmaster legal for deer hunting in straight-wall states?
In many cases, yes. 450 Bushmaster is a straight-walled cartridge, which is why it is popular in states and zones that restrict deer hunting to shotguns, muzzleloaders, and straight-wall rifle cartridges. Regulations vary by state and sometimes by county, so check your state wildlife agency before hunting.
450 Bushmaster vs 350 Legend: which is better?
450 Bushmaster fires much heavier bullets and hits harder, which is an advantage on large deer, hogs, and bear. 350 Legend has less recoil, cheaper ammunition, and runs in standard AR-15 magazines. Both are straight-wall deer cartridges, so the choice comes down to power versus recoil and cost.
More About 450 Bushmaster Ammo
450 Bushmaster grew out of Jeff Cooper's "Thumper" concept: a big-bore cartridge for a semi-auto rifle that could reliably take large game at practical hunting distances. Tim LeGendre of LeMag Firearms designed a cartridge to fit the AR-15, Bushmaster licensed it, and Hornady refined and produced the ammunition, which launched in 2007.
The cartridge's popularity surged as Midwestern states opened deer seasons to straight-wall rifle cartridges. Today 450 Bushmaster is chambered in AR-15 uppers, bolt-action rifles like the Ruger American, and single-shot rifles, and it remains one of the most popular choices for hunters in straight-wall states.
