Caliber of the Month: The .450 Bushmaster
Discover the power and versatility of the .450 Bushmaster — a straight-walled, big-bore cartridge ideal for deer and hog hunting in AR-15 platforms. Learn about its ballistics, origins, and why it’s perfect for states with straight-walled cartridge laws.
The .450 Bushmaster: Big-Bore Power in a Straight-Walled Package
If you're looking for a hard-hitting rifle cartridge that’s legal for hunting in states with straight-walled cartridge laws, the .450 Bushmaster should be on your radar. Developed to deliver big-bore performance from an AR-15 platform, the .450 Bushmaster offers serious stopping power in a compact, practical package. Whether you're a hunter in the Midwest or just love thumping performance from your rifle, the .450 Bushmaster delivers.
Origins of the .450 Bushmaster
The .450 Bushmaster was developed in the early 2000s through a collaboration between Tim LeGendre of LeMag Firearms and Hornady. Originally based on LeGendre's .45 Professional, Hornady shortened the case to work with their Flex Tip bullets, resulting in the final .450 Bushmaster design. The goal was to bring a powerful, straight-walled cartridge to the AR-15 platform, capable of taking down big game at moderate ranges.
Ballistics and Performance
The .450 Bushmaster fires a .452-inch diameter bullet, typically weighing 250 to 300 grains. Despite its relatively short case, the cartridge packs a punch:
- Muzzle Velocity: 2,200 – 2,300 feet per second (fps)
- Muzzle Energy: 2,700 – 2,800 foot-pounds (ft-lb)
This performance gives the .450 Bushmaster enough power to ethically take down deer, hogs, and even black bear within 200 yards. It offers a flatter trajectory and greater velocity than other straight-walled options like the .45-70 Government or .350 Legend.
Why Hunters Love the .450 Bushmaster
The .450 Bushmaster has become especially popular in states like Michigan, Ohio, and Indiana, where straight-walled cartridges are required for deer hunting. Its combination of legal compliance, excellent terminal ballistics, and compatibility with AR-style rifles has made it a top choice among modern hunters.
- Hunting: Ideal for deer and hog hunting, especially in dense woods and short-to-mid range environments.
- AR Platform Friendly: Works in modified AR-15 uppers with minimal changes (magazine and barrel).
- Straight-Walled Legal: Compliant with hunting laws in several states that prohibit bottleneck cartridges.
Considerations and Drawbacks
Like any cartridge, the .450 Bushmaster isn’t perfect:
- Recoil: Substantial kick, especially in lightweight rifles.
- Ammo Cost: Generally more expensive and less common than traditional bottleneck rifle rounds.
- Range Limitation: Best within 200 yards due to drop and energy retention.
Conclusion
The .450 Bushmaster is a modern powerhouse designed for hunters and shooters who need big-bore performance in a legal and practical format. If you live in a state with straight-walled cartridge laws or just want a versatile big-game rifle on the AR-15 platform, the .450 Bushmaster offers a compelling blend of power and practicality.
