What is 450 Bushmaster Ammo?
450 Bushmaster ammo is a big-bore rifle cartridge built for hard-hitting power at short to mid-range. It fires a .452-inch bullet from a straight-walled case. That bullet diameter is a key reason it hits with authority.
It was designed to work in the AR-15 platform with the right upper and magazines. That makes it popular for hunters who like modern rifles. It also works in many bolt-action and single-shot rifles.
History of the 450 Bushmaster

The 450 Bushmaster traces back to Tim LeGendre (LeMAG Firearms). The design dates to 2007, with production starting around 2009.
The goal was simple: deliver heavy-bullet performance from a compact rifle system. It filled a niche between handgun-like straight-wall rounds and traditional high-velocity rifle cartridges. That niche still matters today.
Types of 450 Bushmaster Ammunition
Different loads solve different problems. Picking the right 450 Bushmaster cartridges can raise your confidence fast.
Common types you’ll see:
-
FMJ (Full Metal Jacket): Range training and function testing.
-
JHP (Jacketed Hollow Point): Faster upset and wider wound channels.
-
Soft Point / Bonded: Balanced expansion and penetration.
-
Polymer Tip (FTX-style): Reliable expansion with better flight shape.
For range work, FMJ saves money. For hunting, most shooters prefer an expanding bullet. That choice helps with clean harvests.

Design of the Ammunition
.450 Bushmaster cartridges and components
The straight-wall case is the signature. It promotes reliable feeding and consistent ignition in many rifles. The rebated rim also helps the cartridge work with certain bolt faces.
This design favors short-to-mid range power. It does not chase long-range speed. That is why it feels “purpose-built” in thick cover.
What is 450 Bushmaster Ammo Used For?
Most shooters buy 450 Bushmaster rounds for hunting. It’s a strong choice for deer at reasonable ranges. Many also use it for hogs and similar-sized game.
It also shines as a “brush country” option. You get fast handling and heavy impact. That can lower tracking distance when shot placement is good.
Effective Range
Most factory-style discussions place the effective range around 300 yards. Beyond that, the drop becomes steep, and the wind drift grows fast.
Inside 200 yards, the cartridge feels easy to manage. Past 250, you must know your dope. A simple rangefinder helps a lot.
Muzzle Velocity
Velocity depends on the load. A common reference point is the Hornady 250 gr FTX load at about 2,200 fps from a 20-inch barrel.
That speed brings real energy. Hornady lists muzzle energy near 2,687 ft-lb for that load.
For context, that is a serious close-range punch.

450 Bushmaster Ammo vs 45-70
This is a classic comparison because both hit hard. The 45-70 can run very heavy bullets and huge energy, especially in modern loads. The 450 Bushmaster tends to shoot flatter in some common hunting setups.
If you love lever guns, 45-70 ammo is iconic. If you want AR-style handling, the 450 Bushmaster often fits better. Your rifle choice usually decides the winner.

450 Bushmaster Ammo vs 308
The .308 Winchester carries energy farther. It also shoots flatter at a distance. Many comparisons highlight that .308 stays effective much longer.
The 450 Bushmaster plays a different game. It is a “big-hole, big-hit” round for closer hunting. If you hunt open country, .308 ammo usually wins.
Best 450 Bushmaster Ammo for Deer
For deer, I look for three things: reliable feeding, controlled expansion, and repeatable accuracy. A common sweet spot is 250–260 grain hunting bullets. Hornady’s 250 gr FTX is often used as a reference load for performance.
Simple deer-load checklist:
-
Expanding bullet (polymer tip, soft point, or bonded).
-
Consistent velocity you can confirm at the range.
-
Zero at 100 and verify at 200.

Hornady 450 Bushmaster Ammo
Hornady publishes detailed ballistic tables for popular loads. That helps you plan drop and energy with real numbers. Their 450 Bushmaster 250 gr FTX Hornady BLACK data is one of the clearest references online.
If you want a “known quantity” load, Hornady is a strong place to start. You get consistent performance and good documentation. That builds trust fast.
Remington 450 Bushmaster Ammo
Remington has produced 450 Bushmaster offerings over the years, often aimed at hunting. Many shooters look for these loads when they want familiar brand support. Availability can vary by season and run size.
If you see it in stock, it’s smart to buy enough for sight-in plus hunting. That prevents mixing lots mid-season. It also keeps your rifle’s point of impact stable.
450 Bushmaster AR
The .450 Bushmaster was developed for big game hunting with modern rifles.
The AR-15 compatibility is a major reason this cartridge is popular. It was designed to work with standard AR-15 lowers, with the proper upper and magazines.
That gives you fast follow-up shots and easy optics mounting. It also gives you familiar controls. For many hunters, that comfort matters in the moment.
