450 Bushmaster ammunition is one caliber in a recent line of big bore AR 15 cartridges designed for military and law enforcement. The quest for a powerful, one hit fight stopper that’s acceptable for close quarters battle resulted in a number of different calibers coming forward in AR platforms. The 450 Bushmaster was designed by Tim LeGrende of LeMag Firearms. The 450 Bushmaster was licensed by Bushmaster and they produce the upper receivers, complete weapons, and magazines for the cartridge.

450 Bushmaster ammo fires a 260-grain bullet at an impressive 2,100 feet per second. This delivers a massive amount of energy transfer and is incredibly powerful. However, the round is limited in capacity and range. A standard 30-round AR mag requires a specialized follower, and can contain 9 rounds of 450 Bushmaster. The effective range is most often within 200 yards and is a perfect brush cartridge.

The 450 Bushmaster is ideal for close range hunting or large game, like bears, and perfect medium game like white tails, and feral hogs. When in-stock, you'll see our specialty and bulk rounds for sale below:

    Awesome round! Impresses friends every time I bring it out. Hunting performance is great. I've taken a dozen or so hogs with ZERO runners. Maybe a bit too much for the small Whitetail we get here in the south, but with a neck shot you don't tear up too much. Makes a huge hole on the other side, so for me it's strictly hogs. This thing is pretty accurate too. With only a slight hold over at 200yds with a 100yd zero its pretty flexible and groupings can be kept in about an inch to an inch and a half at 100yds. Not bad for a bullet almost half an inch in diameter. All in all its a fun little round, just slightly pricey for showing off to your buddies. Luckily noone wants to shoot more than about 5-10 rounds due to recoil. Wimps! :)
