Understanding 450 Bushmaster Ballistics

The 450 Bushmaster cartridge has gained significant popularity in the firearms community, beloved for its impressive power and versatility in hunting applications.

If you're exploring this powerhouse round, understanding its ballistics is key to appreciating its capabilities fully.

Let's delve into the details that make the 450 Bushmaster a standout choice for hunters and shooting enthusiasts alike.

The .450 Bushmaster is a high-powered, straight-walled cartridge designed for both hunting and tactical applications.

Developed in the early 2000s by Tim LeGendre of LeMag Firearms, the cartridge was later refined and brought to market through a collaboration between Bushmaster Firearms and Hornady.

Purpose and Design

The 450 Bushmaster was created to deliver big-bore stopping power in a compact form, making it an ideal choice for AR-15 platform rifles.

Its design fills the gap between smaller calibers and heavy-hitting big-game rounds, providing a hard-hitting, effective option for medium to large game hunting.

Additionally, it caters to states with hunting regulations that restrict the use of traditional bottlenecked rifle cartridges, making it a popular alternative for deer hunters.

Popular Uses

• Hunting: Highly effective for deer, hogs, and black bear, especially in areas where straight-walled cartridges are required.
• Tactical and Defense Applications: Offers superior stopping power for law enforcement and close-quarters defense.
• AR-15 Compatibility: Designed to work with AR-15 rifles using a modified upper receiver and specialized magazines.

Velocity and Energy
One of the standout features of the 450 Bushmaster is its impressive velocity and energy transfer.

Typically, when using a 250-grain bullet, it can achieve muzzle velocities around 2,200 feet per second, delivering substantial energy upon impact. This makes it highly effective for hunting large game at moderate distances.

Trajectory
The trajectory of the 450 Bushmaster is relatively flat up to about 200 yards, making it suitable for a variety of hunting scenarios.

Beyond this range, shooters should expect a significant drop. Being aware of this trajectory helps hunters make accurate, ethical shots.

Recoil
While the 450 Bushmaster packs a punch, it is known for being manageable in terms of recoil.

This characteristic appeals to hunters seeking power without the punishing recoil often associated with larger calibers.

Accuracy and Range
The effective range for the 450 Bushmaster typically falls within 250 yards, where it maintains sufficient energy for ethical harvesting of game.

Beyond this, bullet drop increases, and energy retention decreases, factors important for maintaining accuracy and efficacy.

Applications in Hunting
The 450 Bushmaster excels in hunting applications, particularly where regulations favor straight-walled cartridges.

Its power and accuracy make it ideal for deer, hogs, and even larger game in suitable conditions. Hunters appreciate its reliability in dense brush and open fields alike.

The bullet’s muzzle velocity is the rate at which it exits the rifle’s barrel, measured in feet per second (fps).

A longer 450 Bushmaster rifle barrel length produces a higher muzzle velocity, as it gives the exploding propellant more time to exert its energy against the projectile.

When a 450 Bushmaster 300 grain bullet is launched from an AR-15 platform carbine with a 16-inch barrel, its velocity will be lower than the same 300 grain bullet fired from a Ruger American bolt-action rifle with a 22-inch barrel.

Bullet weight and design significantly affect how much velocity a projectile will exhibit downrange.

For example, lighter bullets tend to have higher velocities than heavier bullets, and polymer-tipped hollow point boat tail projectiles tend to conserve velocity more efficiently than traditional soft point bullets.

Handloaded rounds can achieve higher velocities than factory-loaded ammo, which is one reason why reloading is so popular among competitive shooters.

The muzzle velocity of a typical 450 Bushmaster cartridge ranges from about 1,900 fps to 2,400 fps, depending on the rifle and load you’re firing.

There are also subsonic rounds that have extremely low muzzle velocities (~1,050 fps) by design.

A bullet’s energy is measured in foot-pounds (ft-lbs). Muzzle energy is the force a bullet possesses when it leaves the rifle barrel.

Heavier bullets tend to have higher muzzle energy, although the projectile’s velocity plays a significant role. For example, a 260 grain soft point has a higher muzzle energy (2,794 ft-lbs) than a 300 grain jacketed hollow point (2,405 ft-lbs).

However, at 300 yards, the heavier projectile (300 grain JHP) will have conserved more of its energy (860 ft-lbs) compared to the 260 grain SP (770 ft-lbs).

Whichever round you choose for your Ruger, Savage Arms or Winchester, the 450 Bushmaster can be a shoulder-thumper.

Because the 450 Bushmaster was designed for taking large game in states that require straight-walled cartridges for hunting, its effective range and ballistic data might remind you of a magnum handgun cartridge which Henry, Marlin and Winchester lever-action rifles are commonly chambered for.

The effective range of the 450 Bushmaster is about 300 yards. Beyond this distance, the bullet drops so much that it becomes extremely inaccurate.
