What is 450 Bushmaster?

The .450 Bushmaster is a rifle cartridge designed for big-game hunting and AR-15 platform rifles. It was developed by Tim LeGendre of LeMag Firearms and later licensed by Bushmaster Firearms International. The cartridge was specifically created to offer significant stopping power at short to medium ranges.

The .450 Bushmaster has a bullet diameter of .452 inches (11.5 mm) and a case length of 1.7 inches (43 mm).

One of the primary purposes of the .450 Bushmaster is to provide a powerful cartridge for hunting large game, such as deer, boar, and other similar-sized animals, at relatively close distances. It is capable of delivering excellent terminal performance, with heavy bullets that expand well and penetrate deeply. The cartridge’s design allows it to be used in standard AR-15 rifles with a modified upper receiver and appropriate magazines.

Due to its power and versatility, the .450 Bushmaster has gained popularity among hunters who prefer the AR-15 platform and require a hard-hitting cartridge for taking down game in dense brush or wooded areas. It offers a good balance between manageable recoil and stopping power, making it effective within a range of around 200 yards.

It’s worth noting that laws and regulations regarding the use of specific cartridges for hunting can vary by jurisdiction, so it’s important to familiarize yourself with the regulations in your area before using the .450 Bushmaster or any other cartridge for hunting purposes.

When it comes to accuracy, both the 350 Legend and the 450 Bushmaster have their pros and cons. The 350 Legend has a flatter trajectory and less recoil, making it easier to shoot accurately at longer ranges.

This is due in part to its smaller bullet size and faster velocity. However, the 450 Bushmaster has a heavier bullet and more energy, which can make it more accurate at shorter ranges and better for hunting larger game.

In terms of ammunition, the 350 Legend is more commonly available and has a wider variety of loads, which can make it easier to find the right load for your specific firearm and shooting needs.

When comparing the 350 Legend and the 450 Bushmaster, recoil is an important factor to consider. Recoil refers to the backward movement of the firearm after a shot is fired. This can impact accuracy, as well as the shooter’s comfort and ability to handle the firearm.

The 350 Legend has been touted for its low recoil, making it a popular choice for hunters and shooters of all levels. This is due in part to the cartridge’s design, which features a straight-walled case and a relatively low powder charge. The result is a cartridge that delivers less felt recoil than other popular hunting rounds, such as the 308 Winchester.

The 450 Bushmaster, on the other hand, is known for its significant recoil. This is due in part to the cartridge’s larger size and heavier bullet. While some shooters may find the recoil manageable, others may find it uncomfortable or even painful to shoot for extended periods of time.

Ultimately, the recoil of a firearm is a subjective experience that can vary depending on factors such as the shooter’s size and strength, the weight of the firearm, and the type of ammunition used. However, for those who are particularly sensitive to recoil or looking for a more comfortable shooting experience, the 350 Legend may be the better choice.

When it comes to availability, the 450 Bushmaster has a slight advantage over the 350 Legend. This is because the 450 Bushmaster has been around for a few years longer, and it has had more time to establish itself in the market. As a result, there are more options available when it comes to ammunition, and it is easier to find 450 Bushmaster rounds at your local gun store or online retailer.

However, this does not mean that the 350 Legend is difficult to find. In fact, the 350 Legend has gained a lot of popularity in a short amount of time, and it is quickly becoming a favorite among hunters and shooters. Many major ammunition manufacturers, such as Winchester and Hornady, have started producing 350 Legend rounds, and they are widely available at most gun stores and online retailers.

It is also worth noting that the 350 Legend has some advantages over the 450 Bushmaster when it comes to ammunition. For example, the 350 Legend is capable of shooting bullets with a higher ballistic coefficient, which means they retain their energy and trajectory better over long distances. Additionally, the 350 Legend is capable of shooting bullets at higher velocities than the 450 Bushmaster, which can be beneficial for certain types of hunting and shooting situations.

Overall, both the 350 Legend and the 450 Bushmaster are capable cartridges with unique features and capabilities. When it comes to ammunition availability, the 450 Bushmaster has a slight advantage, but the 350 Legend is quickly catching up and is widely available at most gun stores and online retailers.


When it comes to price, the 350 Legend and 450 Bushmaster are fairly comparable. Both cartridges are relatively new to the market, and as such, they are not as widely available as some of the more established calibers. However, there are still a number of options out there for those looking to purchase ammunition for either cartridge.

On average, the cost of 350 Legend ammunition is slightly lower than that of 450 Bushmaster ammunition. This is likely due in part to the fact that the 350 Legend uses a smaller bullet, which requires less material to produce. However, the difference in price is not significant enough to be a deciding factor for most shooters.

It is worth noting that the cost of ammunition can vary depending on a number of factors, including the brand, the specific load, and the retailer. As such, it is always a good idea to shop around and compare prices before making a purchase.
