Some hunters want a rifle cartridge that is guaranteed to bring down their target no matter what, believing that bigger is oftentimes better. For these hunters and marksmen, the 450 Bushmaster cartridge is a perfect choice. It’s designed to be used by AR 15 and M16 weapon platforms as a high-power, short-range cartridge that’s perfect for taking down moving targets consistently.

It’s powerful enough to take down larger game and delivers a booming retort, causing some hunters to call it the “Thumper” cartridge. Indeed, it boasts considerable recoil.

The right scopes for this high-power cartridge don’t have to be hard to locate now that you’ve found this guide. Below, we’ve collected the best 450 Bushmaster scopes on the market for you to browse, plus put together a quick set of tips to help you determine the best scope for your needs. Let’s get into it.

Things to Consider Before Buying a 450 Bushmaster Scope

Above all other uses, the .450 Bushmaster is designed for hunting within typical engagement ranges of about 300 yards to 500 yards, although it’s certainly effective at ranges below or significantly above this ideal zone. To that end, let’s look at the major aspects to keep in mind as you browse.

Magnification Settings

The best scope for 450 Bushmaster weapons will complement the cartridge’s capabilities well. We wouldn’t recommend looking for scopes that use above 15x magnification for use with a 450 Bushmaster, although your mileage may vary. Overall, you’ll want to target scopes that are suitable for close-range engagements or for hunting moving targets.

That’s why the scopes we chose below are perfectly designed for these kinds of purposes. There’s no single magnification range perfect for every hunter, but you can find several scopes with different zoom levels, offering you some flexibility for your choice.

Eye Relief

The 450 Bushmaster provides quite a hefty kick each time it’s fired. Because of this, the best 450 Bushmaster scopes will provide you with plenty of eye relief. But what exactly is that?

Eye relief is the maximum distance at which you can rest your eye and still get the total picture from your scope. This safe distance makes it safe for you to fire with your eye still “in” the scope but not be hurt by the scope jerking back and slamming into your orbital bone.

Higher amounts of eye relief are usually better when used with a high recoil cartridge like this one. We selected scopes with great eye relief across their magnification settings, but you’ll never want to go below 2 inches or so. All of the scopes we selected have eye relief of at least 3 inches or more.


If you’re planning on taking your 450 Bushmaster scope with you on your next hunting engagement, you’ll probably want something built to last. Hunting takes place in a variety of environments and oftentimes in inclement weather. To this end, getting a scope that can withstand the elements and stick with you throughout the entirety of a hunt is crucial to your success.

Below, you’ll find some excellent scopes that have waterproof or fog proof constructions. This allows the scope to continue to function even in terrible weather conditions. But many of the best 450 Bushmaster scopes will also have durable lenses that have protective coatings that can reduce their abrasion damage or improve their light transmission.

Naturally, we only selected scopes that have these upgrades or similar durability improvements for your consideration. Hunting scopes need to be able to put up with some punishment just like you can, and that goes double for 450 Bushmaster scopes, which also have to contend with the high recoil that comes with every shot.

First or Second Focal Plane

Finally, consider whether a given 450 Bushmaster scope has a reticle on the first or second focal plane. First focal plane reticles can be useful because they change size and have holdover points that remain accurate as you flip between zoom levels. They can be difficult to get used to, however.

Second focal plane reticles are more consistent in that they do not change sizes as you switch between zoom levels. But their holdover points are only accurate for one magnification setting, so you have to estimate the real windage or elevation adjustments as you swap between levels.

All in all, hunters can prefer either type of reticle, so we provided scopes with both types below for your consideration. Either can be effective on a hunt in the right hands.

Frequently Asked Questions

Does the 450 Bushmaster have a lot of recoil?

A 450 Bushmaster upper is a powerful weapon. When shooting through a lightweight rifle like the AR-15, the power factor of.450 isn’t far off from 12-gauge slugs, and you’ll notice it.

Fortunately, there are a few simple solutions to the problem. First and foremost, a muzzle break will significantly dampen the felt recoil although you’ll definitely want a good pair of muffs, and a non-slip butt stock with a bit of rubber will make a huge difference compared to the solid plastic or metal of your average mil-spec stock. A heavier buffer, such as an H2 or H3, can also help to reduce recoil.

What is a straight-walled cartridge?

Straight-walled cartridges, such as the .450 Bushmaster and 350 Legend, have sides that are the same diameter from front to back, as the name implies. When looking at the cartridge from the side, you’ll notice a straight line running from the rim to the end of the case, narrowing only at the bullet. 

A bottlenecked cartridge, on the other hand, will taper down because the case diameter is larger than the diameter of the bullet. The “shoulder” is the most visible feature of a bottlenecked cartridge.

What is a bottleneck?

A bottleneck cartridge, in essence, will have more propellant behind the bullet, allowing it to fire at higher velocities, resulting in longer effective ranges. However, this raises the risk of overshooting; if a hunter misses the target, the bullet may go downrange, causing damage, injury, or even death. 

As a result, many states have made it unlawful to hunt with bottlenecked cartridges. Especially in the Midwest, hunting sites are frequently littered with farm buildings, animals, and other facilities. Many Midwest states have declared hunting with bottleneck cartridges like the.30-06 Springfield illegal, in contrast to western states, which are often more open and unoccupied.

Who made the 450 Bushmaster?

The 450 Bushmaster is part of the legacy of Jeff Cooper, a Marine Corps veteran who went on to become a ballistics expert and weapons instructor after serving in WWII and Korea. He formed the American Pistol Institute and developed a number of pistol carrying, handling, and shooting techniques. Cooper’s proposal for a “thumper” round was one of his many contributions. For huge game animals, shooters utilize thumper bullets in semi-automatic rifles to offer additional power, but not necessarily speed.

Cooper never went beyond the concept, but the idea was picked up by multiple cartridge manufacturers, who eventually issued the round after various case length adjustments. 450 Bushmaster ammo is currently produced by only two companies: Federal and Hornady.

Although hunting with the cartridge has been illegal in many locations for years, recent revisions in state legislation have made it permissible for harvesting whitetail deer, resulting in a considerable increase in the cartridge’s use.

What is the 450 Bushmaster used for?

The 450 Bushmaster is utilized for two distinct sports: medium to large game hunting and competitive target shooting. Shooters are mostly interested in how it compares to other straight-walled rifle cartridges, which are popular among hunters. However, it’s also worth contrasting the cartridge with other high-volume target shooting rounds.

Concluding our Best  Scope for 450 Bushmaster Guide

The right scope paired with your 450 Bushmaster platform will make you a force to be reckoned with! Whether you just like cartridges that go “boom” or you’re looking to put down some heavier game, you should now be ready to take home the prize on your next hunt. Good luck!
