What is .450 Bushmaster?
The .450 Bushmaster is a straight-walled cartridge with ballistics similar to the noble .45-70 Government. This makes it a smart choice for deer hunting, especially in areas where bottle-necked ammo is restricted.
Inspired by Jeff Cooper’s popular “Thumper” concept, the .450 BM cartridge was developed by Tim LeGendre to produce one-shot kills on big game. Unsatisfied with the performance of .223 Remington/5.56x45mm NATO cartridges, Cooper and LeGendre wanted a big bore option that would cycle through semi-automatic rifles. The .450 Bushmaster definitely fits the bill.
One reason .450 Bushmaster has become so popular is because it can be fired from AR platforms. All you need is a new upper and your AR-15 is transformed into a powerful, big-bore hunting rifle. The process only takes about fifteen minutes. You get to keep your lower receiver and your magazines. .450 Bushmaster cartridges should run through them like they were made for each other.
The .450 Bushmaster cartridge also performs well in traditional bolt-action rifles. Shooters can find quality .450 BM bolt actions from Ruger, Remington, Savage, and Mossberg.
Finding the Right Optic for .450 Bushmaster
When choosing an optic for any rifle, the most important thing to consider is what the rifle will be doing. The .450 Bushmaster is usually used for one of two applications - hunting large game or target shooting. How you plan to use your rifle will play a large part in what type of scope you should mount on your firearm.
No matter what your shooting style, it’s important to keep in mind that the .450 Bushmaster packs a pretty powerful punch. Expect recoil similar to a 20-gauge shotgun. You’ll need a shockproof optic with enough hutzpa to handle some kick.

1 Vortex Optics Strikefire II Red Dot
Red dot sights and AR-15s go together like peanut butter and jelly, so if you’re running an AR chambered in .450 Bushmaster, the Vortex Strikefire II deserves some serious consideration.
This affordable, scope-style red dot works well for both hunting and tactical applications. It features a highly visible, 4 MOA red dot with ten different brightness settings. The lenses are fully multi-coated to provide a crisp, bright field of view.
The main housing of the Strikefire II is constructed from a single piece of aircraft grade aluminum with a matte black, hard-anodized finish. The finish helps the optic resist scuffs, scratches, and corrosion. The whole thing is nitrogen-purged and o-ring sealed, making it fully waterproof, fogproof, shockproof. This thing is as rugged as they come.
2 Aimpoint CompM4s Red Dot
This combat-proven optic from Aimpoint was one of the first red dot optics issued to the US military for use with night vision. Made from extruded, high-strength aluminum with a hard anodized finish, this optic holds up in the harshest environments. The CompM4s is even water-resistant to 150 feet. You could conceivably go snorkeling with this red dot without wrecking it!
The front lens on the CompM4s has a unique band-pass coating that perfectly reflects certain frequencies of red light. This ensures a brilliant dot without draining undue battery power. The coating also transmits nearly 100 percent of light in the infrared and near infrared spectrum, making the CompM4s perfect for running your AR with Gen 3 night vision.
To optimize reticle visibility in any setting, the CompM4s features seven NVD-compatible brightness settings and nine daylight settings.
3 Eotech EXPS2 Holo Sight

The optics giant Leupold answered the call with this version of their popular VX-Freedom riflescope. It features an elevation dial designed to match the ballistic bullet drop of the most popular .450 Bushmaster loads. This takes much of the guesswork out of longer range shooting.

The best way to become a better shooter is to practice, practice, and then practice some more.
