Description
Federal Fusion ammunition was the first rifle round built specifically for hunting, and it's earned its reputation through genuine field performance. The .450 Bushmaster has become popular with hunters working in states that require straight-wall cartridges, and this 260-grain Fusion load delivers the kind of terminal performance the cartridge was designed for.
The bonded-core technology is the real story here. Federal uses an electrochemical process to fuse the lead core directly to the copper jacket, preventing separation even through heavy bone. That means more weight retention and deeper penetration on game. The skived, pre-programmed nose cavity provides controlled expansion that starts reliably even at lower velocities, a feature that matters when you're working with the Bushmaster's typical engagement distances. At 2,200 fps, you're getting 2,794 foot-pounds of muzzle energy, which translates to real knockdown power in the field.
Federal Fusion Soft Point Construction
What makes the Fusion line work is the engineering behind that bonded design. The uniform copper jacket applied electrochemically means better accuracy shot-to-shot, and the pressure-formed core works with the jacket to deliver maximum energy transfer when the bullet does its job. This isn't a budget load relying on old cup-and-core construction where the jacket and core separate unpredictably. You get consistent results that have earned Fusion a solid following among serious hunters.
Performance for Big Game
The .450 Bushmaster at 260 grains sits in that sweet spot for deer, hogs, and similar-sized game out to reasonable hunting distances. Each 20-round box comes in reloadable brass, so if you reload, you're getting usable empties along with the loaded ammunition.

Frequently Asked Questions
What makes the Federal Fusion bullet different from standard hunting ammunition?
Federal Fusion uses an electrochemical bonding process to fuse the lead core directly to the copper jacket, preventing jacket-core separation. This design delivers higher weight retention and deeper penetration compared to traditional cup-and-core bullets, giving you more reliable terminal performance.
Is Federal Fusion .450 Bushmaster ammo suitable for all hunting situations?
The 260-grain Fusion load works well for deer, hogs, and similar medium game out to typical hunting ranges of 200-250 yards. The .450 Bushmaster was designed for states requiring straight-wall cartridges, so it's ideal if that's your legal requirement. For longer-range hunting or larger game, you may want to consider heavier bullet weights.
Can I reload these brass casings?
Yes, the ammo comes with reloadable brass cases. Standard reloading dies work with .450 Bushmaster brass. Just follow current reloading data for the Fusion bullet design, as the bonded construction may generate standard pressures similar to other jacketed bullets.
How does the 260-grain Fusion compare to other .450 Bushmaster loads?
The 260-grain Fusion soft point is one of the lighter hunting loads available for the Bushmaster. It delivers slightly higher velocity (2,200 fps) and higher muzzle energy (2,794 ft-lbs) compared to heavier 300-grain options. This makes it better for extended range while still maintaining solid terminal performance on medium game.
