Federal Fusion 308 Winchester ammunition with 180 grain bonded round nose projectiles pairs controlled expansion with deep penetration for hunters taking whitetail, mule deer, black bear, and similarly sized game in wooded or brushy terrain. The electrochemical bonding process fuses the lead core to the copper jacket at the molecular level, eliminating the jacket-core separation that compromises weight retention in conventional cup-and-core designs. At 2600 feet per second muzzle velocity and 2700 foot-pounds muzzle energy, this load drives consistent performance from bolt-action and semi-automatic rifles with 20- to 24-inch barrels. Federal Premium Ammunition manufactures Fusion in the United States using boxer-primed brass cases — reloadable for shooters who handload their own hunting rounds.
Performance at a Glance
The 180 grain bonded round nose bullet features a dimpled nose cavity that initiates reliable expansion at velocities above 1800 fps while the bonded construction holds the projectile together through bone, muscle, and hide. Round nose profile reduces air resistance in brush, maintaining trajectory stability when branches or tall grass intercept the bullet path before it reaches the target. Brass cases shed heat efficiently during extraction, and the non-corrosive boxer primer seats flush for reliable ignition in temperature extremes from 10°F to 100°F.
