5 Best 450 Bushmaster Magazines (2022) – Pick the Right One

The .450 Bushmaster is a respectable and yet hugely overlooked caliber on the market today. Though originally designed to provide the AR-15 platform with a lot more firepower to bring down a big game, the .450 Bushmaster ammo is now available for many different firearms beyond just the AR-15, including bolt action rifles such as the Ruger GSR and Ruger American.

450 Bushmaster magazines provide hunters with extra carrying capacity to take down larger game and in some states, it may be the only way for people to legally hunt with a rifle. However, before you purchase a new magazine to achieve this capability, you need to understand the basics behind these magazines and make sure you’re purchasing only the best.

Benefits of Carrying Extra 450 Bushmaster Magazines

It is a well-known fact that carrying spare magazines is always an excellent idea. In the case of a .450 Bushmaster, it’s an even smarter idea to carry extra mags. Here are a few reasons why:

Better Versatility

One possibility with the 450 Bushmaster is that you don’t have to carry the same magazines every time. The .450 bushmaster can be rather unwieldy, so having mags that perform differently is a great way to adapt to any situation.

More Rounds

Though many states don’t allow this and have a cap to the number of rounds you can carry, anytime you have an opportunity to increase your magazine size, it is highly recommended for you to seriously consider it. More shots will mean less time and effort spent on reloading.


450 Bushmaster magazines can sometimes jam and if something goes wrong with your existing magazine mid-shot, you may just lose the target if you aren’t able to quickly swap out with a spare magazine on hand.

Learning Curve

Many hunters that have upgraded to the .450 Bushmaster will know that there’s a bit of a learning curve to mastering this firearm. In other words, you’ll probably need extra shots at first to practice and you’ll save yourself the time with spare mags.


Guns and firearms can occasionally be an expensive sport/hobby. However, having magazines is one of the most affordable ways to make your life easier. So, you should definitely take advantage of cheap upgrades whenever you can.

Aspects to Consider when Buying .450 Bushmaster Magazines

When shopping for a new .450 Bushmaster magazine, you shouldn’t just purchase any one right off the shelf. You should get the right product that’s perfect for your needs. To help you decide, here are a few factors you can pay attention to:

Feed Performance

The .450 Bushmaster is one type of magazine where reliability really matters. For too many .450 Bushmaster magazines have been reported to not feed properly. Fortunately, we’ve gathered some of the best .450 Bushmaster magazines available on the market that you can count on in this article.


The design of a .450 Bushmaster mag will tie in directly with its feed performance. The geometry of most ammo brands features a taper that does not feed well in certain rifles such as the AR. While it’s not to say that these are bad brands, you need to check that the .450 Bushmaster magazine design is compatible with your gun’s design for reliable performance. You shouldn’t encounter any problem with a quality bolt action magazine or single-shot rifles but it may be a different story altogether when it comes to semi-automatics.


One of the most important aspects of a magazine is obviously its capacity. Be sure to get the right number of rounds in a magazine that you want or desire to fit your requirements.


Fortunately, magazines are not very expensive. So, make sure you’re not spending an arm and a leg for what should be a good value component of the firearm.
