Description
Federal Fusion ammunition delivers real terminal performance at a price that makes sense. This load pairs a 180-grain bonded soft-point bullet with a molecularly fused jacket and pressure-formed core, engineered specifically to work on deer-sized game where it counts most.
How Fusion Bullets Perform
The core construction is what sets Fusion apart. The lead core bonds completely to the copper jacket through an electrochemical process, eliminating the risk of core/jacket separation that can happen with other designs. A skived nose cavity controls expansion reliably, producing consistent mushrooming with exceptional weight retention. In ballistic gelatin testing, Fusion bullets expand significantly while retaining around 90 percent of their original weight, which translates to deep penetration and reliable performance in the field.
Ballistics and Accuracy
Loaded to 2,950 feet per second with 3,478 foot-pounds of muzzle energy, the 180-grain load carries plenty of power downrange. The boat-tail profile helps the bullet fly flat and resist wind, improving accuracy at typical hunting distances. A ballistic coefficient of .484 provides a flat trajectory you can rely on. This load prints well in most rifles and has earned a reputation among hunters for consistent accuracy.
Built to Last
Federal loads this round with non-corrosive boxer-primed brass cases that are fully reloadable. New production ammunition means you're getting fresh components and consistent quality control from a manufacturer with decades of experience building hunting ammunition.

Frequently Asked Questions
What makes Fusion ammunition different from other bonded bullets?
The jacket and core are molecularly fused together through an electrochemical bonding process rather than just mechanically joined. This means the jacket and core won't separate during impact, giving you consistent expansion and excellent weight retention that leads to deep, reliable penetration on game.
Is Federal Fusion ammunition reloadable?
Yes. The brass cases are boxer-primed and fully reloadable. Federal loads all Fusion rounds with new production brass and quality primers, so after you fire them, you can reload the cases with your own components.
What size game is 300 WSM with 180gr Fusion best suited for?
This load was engineered for whitetail and similar-sized deer. The 180-grain weight gives you plenty of energy for reliable expansion at typical hunting ranges, with excellent penetration characteristics. The design is optimized to perform on medium game rather than larger species like elk.
How does accuracy compare in typical hunting rifles?
Fusion loads have a reputation for solid accuracy in most quality rifles. The 2,950 fps velocity is moderate for the cartridge, which often contributes to easier shooting and more consistent bullet performance. Many hunters report reliable sub-minute-of-angle groups when the rifle and shooter combination allows it.
