The .450 Bushmaster: A Comprehensive Guide to Performance, Ballistics, and Applications
The .450 Bushmaster is a powerful, straight-walled cartridge designed for AR-15 platform rifles, offering hunters and sport shooters a potent option for taking down large game at moderate ranges. Developed by Tim LeGendre of LeMag Firearms and later popularized by Bushmaster Firearms International, the .450 Bushmaster addresses the need for a cartridge that meets specific hunting regulations in states that restrict the use of bottlenecked cartridges. This article provides a comprehensive overview of the .450 Bushmaster, covering its history, ballistics, performance, applications, and considerations for those looking to adopt this formidable round.
History and Development of the .450 Bushmaster
The story of the .450 Bushmaster begins with a problem: many Midwestern and Eastern states had regulations prohibiting the use of bottlenecked cartridges for deer hunting, due to perceived safety concerns and the desire to limit effective range. This restriction left hunters with limited options, often relegated to shotguns with slugs or muzzleloaders. Tim LeGendre recognized this gap in the market and set out to develop a cartridge that would be legal in these states while still delivering sufficient power for ethical and effective deer hunting. Collaborating with Bushmaster, the .450 Bushmaster was born, offering a viable solution for hunters in restricted areas.
Initially, the cartridge faced some skepticism, but its performance in the field quickly won over hunters. The .450 Bushmaster proved to be accurate and effective at ranges suitable for most whitetail deer hunting scenarios. Bushmaster’s decision to chamber their AR-15 rifles for the .450 Bushmaster further solidified its popularity, making it accessible to a broad audience. The .450 Bushmaster cartridge is now a common choice in many states with straight-walled cartridge restrictions.
Ballistics and Performance of the .450 Bushmaster
The .450 Bushmaster is characterized by its large-diameter bullet and relatively low velocity. Typically, it fires a 0.452-inch diameter bullet weighing between 250 and 300 grains at velocities ranging from 2,200 to 2,400 feet per second. This combination results in significant energy transfer to the target, making it highly effective on large game. Understanding the ballistics of the .450 Bushmaster is crucial for making informed decisions about its suitability for different hunting and shooting applications.
Effective Range
The .450 Bushmaster is primarily a short-to-medium range cartridge. Its effective range is generally considered to be within 200-250 yards. Beyond this distance, bullet drop becomes significant, and energy levels diminish. While it’s possible to make accurate shots at longer ranges with proper ballistics calculations and practice, the .450 Bushmaster truly shines within its intended range.
Trajectory
The trajectory of the .450 Bushmaster is relatively flat out to around 150 yards, making it easy to aim and shoot accurately. However, beyond this distance, the bullet drop increases noticeably. Hunters need to be aware of this trajectory and adjust their aiming point accordingly to ensure accurate shot placement. Ballistic charts and rangefinders can be valuable tools for compensating for bullet drop at longer distances.
Energy and Stopping Power
One of the .450 Bushmaster’s key strengths is its impressive energy and stopping power. The heavy bullet delivers a substantial amount of kinetic energy to the target, resulting in rapid incapacitation. This makes it an excellent choice for hunting large game such as deer, hogs, and even black bear. The .450 Bushmaster provides humane and ethical kills when used within its effective range.
Applications of the .450 Bushmaster
The .450 Bushmaster cartridge’s primary application is hunting, particularly in states with straight-walled cartridge restrictions. However, its versatility extends beyond hunting, making it suitable for various shooting activities.
Hunting
The .450 Bushmaster is a popular choice among deer hunters in states like Michigan, Ohio, Indiana, and Iowa, where straight-walled cartridge rifles are permitted. Its large bullet diameter and substantial energy make it highly effective on whitetail deer. Additionally, the .450 Bushmaster is also suitable for hunting wild hogs, which are becoming increasingly prevalent in many parts of the United States. Its stopping power ensures quick and ethical kills, even on tough and resilient hogs.
Sport Shooting
While primarily designed for hunting, the .450 Bushmaster can also be used for sport shooting activities. Its manageable recoil and inherent accuracy make it enjoyable to shoot at the range. Some shooters also use it for recreational target shooting and even in certain shooting competitions that allow straight-walled cartridges. The .450 Bushmaster offers a unique shooting experience compared to smaller-caliber cartridges.
Home Defense
Although not its primary purpose, the .450 Bushmaster can be considered for home defense in certain situations. Its significant stopping power makes it a formidable deterrent against potential threats. However, its over-penetration potential should be carefully considered, as the bullet can easily pass through walls and pose a risk to bystanders. Responsible gun owners should carefully evaluate their specific needs and circumstances before choosing the .450 Bushmaster for home defense.

Considerations When Using the .450 Bushmaster
While the .450 Bushmaster is a powerful and effective cartridge, there are several considerations to keep in mind when using it:
- Recoil: The .450 Bushmaster produces significant recoil, which can be challenging for some shooters. Proper shooting technique and the use of a recoil pad can help mitigate the effects of recoil.
- Ammunition Availability: While .450 Bushmaster ammunition is becoming more readily available, it may not be as widely stocked as more common cartridges like .223 Remington or 30-06 Springfield. Plan ahead and ensure you have an adequate supply of ammunition before heading out to the range or into the field.
- Over-Penetration: The .450 Bushmaster’s powerful bullet can easily penetrate through walls and other barriers, posing a risk to bystanders. Be mindful of your surroundings and ensure you have a safe backstop when shooting.
- Range Limitations: The .450 Bushmaster is primarily a short-to-medium range cartridge. Avoid taking shots beyond its effective range to ensure ethical and accurate shot placement.
