Federal Premium HammerDown .45 Colt 250gr Bonded Hollow Point ammunition is purpose-built for lever-action rifles, the workhorse platform that defines American hunting tradition. Unlike generic centerfire handgun rounds adapted for rifle use, HammerDown loads are engineered from the ground up to cycle reliably through tubular magazines and side-gate loading systems while delivering consistent terminal performance. If you run a Henry, Marlin, or Winchester lever gun in .45 Colt and want ammo that feeds like it was made for your rifle—because it was—this is the round that changes the game.
The 250-grain bonded hollow-point bullet is optimized for the velocities these rounds achieve in lever-gun barrels, ensuring reliable expansion and weight retention on impact. Federal paired this projectile design with a nickel-plated case and modified chamfered case geometry that eliminates feed resistance through tubular magazines. You get better accuracy, smoother cycling, and terminal ballistics tuned to how your lever gun actually shoots—not a one-size-fits-all compromise.
Developed in partnership with Henry Repeating Arms and loaded to 1400 feet per second, HammerDown ammunition respects the mechanical realities of lever-action feeding while maximizing what these rifles can deliver downrange. Whether you're hunting hog, deer, or testing your iron-sighted rifle at distance, you're running ammo that was designed for your gun, not retrofitted to it. Each box contains 20 rounds ready to load.
