Overview of 450 Bushmaster Ammo

450 Bushmaster ammo was designed for shooters who want hard-hitting stopping power from a semi-automatic platform — specifically the AR-15. Originally developed for straight-wall hunting states and large game, this round combines deep penetration, high energy, and impressive terminal ballistics in a compact package.

Why Choose 450 Bushmaster?

The 450 Bushmaster fires a .452-inch diameter bullet, usually weighing between 250 and 300 grains, with muzzle velocities ranging from 1,800 to 2,200 feet per second. It delivers over 2,700 foot-pounds of energy at the muzzle — putting it in the same league as traditional big-bore hunting cartridges, but in a lighter, faster-shooting rifle.

It's an excellent option for hunters and ranchers who need to take down hogs, whitetail, black bear, or even elk at moderate ranges — especially where regulations require straight-walled cartridges.

Common Uses for 450 Bushmaster Ammo

  • Hunting: Ideal for short- to mid-range hunting of large game — including deer, hogs, and black bear.
  • Home and Property Defense: Delivers significant stopping power in a modern sporting rifle (MSR) platform.
  • Brush Guns: Great for thick woods or brush where shots are under 150 yards and fast follow-ups matter.

.450 Bushmaster Ballistics

Ballistically, 450 Bushmaster delivers a strong, straight trajectory out to about 200 yards, depending on barrel length and load. It offers significantly more knockdown power than standard intermediate cartridges like 223 or 5.56, making it ideal for hunters in dense brush or areas where quick, ethical takedowns are critical.

How Does 450 Bushmaster Compare?

Still deciding if 450 Bushmaster is the right fit? Here’s how it stacks up against other popular rifle calibers:

  • 350 Legend vs. 450 Bushmaster – 350 Legend has less recoil and flatter trajectory, but 450 Bush delivers more energy and better performance on larger game.
  • 450 Bushmaster vs. 458 SOCOM – .458 SOCOM offers heavier bullets and more subsonic options, while 450 Bushmaster usually wins in velocity and longer-range accuracy.
  • 450 Bushmaster vs. 308 – 308 has better long-range performance, but 450 Bushmaster delivers more energy at close range and is legal in more straight-wall-only states.
  • 450 Bushmaster vs. 223 – 223 offers lower recoil and higher capacity, but 450 Bushmaster absolutely dominates in stopping power and penetration.

Is 450 Bushmaster Ammo Right for You?

If you need a powerful, reliable cartridge that delivers serious punch from an AR-15 platform, and you’re hunting in states that require straight-walled ammo, 450 Bushmaster is hard to beat. It may kick more and cost more than smaller calibers, but for many hunters and rural defenders, the trade-off is worth it.
