450 Bushmaster Ammo from Top Brands like Remington, Federal, and Winchester — 17 products / 18 models

With such a large caliber bullet, 450 Bushmaster ammo is a big-game hunting round designed for the AR-15, a rifle that is traditionally chambered for the small caliber high velocity 223/5.56 cartridge. The 450 Bushmaster round was named after the bullet's size and the rifle brand that originally chambered it. You can fire .450 Bushmaster ammo out of any AR rifle. All you need to do is swap out the upper receiver on your AR and use a modified magazine.image

The creators of 450 Bushmaster ammo designed it for one-shot kills on big game like deer or elk at ranges out to 250 yards. On paper, a 450 bullet weighing 250 grains will deliver a muzzle velocity of 2,200 feet per second with 2,686 foot-pounds of energy. At 300 yards, it will maintain a velocity of 1,255 fps with 874 ft-lbs of energy.
