Federal Premium HammerDown .327 Federal Magnum ammunition brings specialized design to one of the most capable lever-gun cartridges in modern shooting. This 127-grain bonded soft-point load is engineered specifically for the reliable, smooth cycling that lever-action shooters demand—addressing the unique feeding and ballistic requirements that factory ammo often overlooks. Whether you run a Henry or another quality lever gun, HammerDown rounds are built to feed flawlessly and perform on game.
The ammunition's design centers on practical reliability. A modified chamfered case eases feeding through side-gate loading and tubular magazines, eliminating the feeding hiccups that can plague lever guns with standard rifle rounds. The bonded soft-point bullets are tuned for the velocity window and barrel lengths typical of lever-action rifles, delivering consistent expansion and weight retention when it matters. Nickel-plated cases resist corrosion and simplify unloading and reloading if needed.
For hunters and shooters who trust lever guns—whether for hunting, ranch work, or backcountry use—HammerDown ammo is purpose-built to maximize what your rifle can do. The .327 Federal Magnum round offers a potent balance of power and control, and Federal's engineering ensures you get the most from it without the reliability compromises of generalist ammunition.

Yes. HammerDown ammunition is specifically engineered for lever-action feeding systems, with a modified chamfered case designed to feed flawlessly through tubular magazines and side-gate loading mechanisms—the standard configurations on most lever guns.
This is .327 Federal Magnum ammunition. The .327 Federal Magnum is a capable handgun and rifle cartridge; when loaded into a lever-action rifle, the 127-grain bonded soft point is suitable for hunting medium game and varmint applications where appropriate shot placement is made.
HammerDown loads are optimized specifically for lever-action rifles. The bullet is bonded for reliable expansion at velocities typical of lever-action barrels, the case geometry and chamfer support reliable feeding through lever magazines, and the overall design accounts for how these rifles perform—not as an afterthought, but as the primary design intent.
Nickel plating provides corrosion resistance and can make cases easier to extract and clean after firing, which is a practical benefit in the field or if you plan to reload.
