If you run a lever gun in .327 Federal Magnum, Federal Premium's HammerDown line was built specifically for your rifle. This isn't just another box of ammo that happens to work in your gun. The ammunition scientists at Federal collaborated directly with Henry Repeating Arms to create a complete package tuned to what modern lever-action shooters actually need.
The case geometry on these rounds is noticeably different from standard ammunition. Federal modified the case rim with a slight chamfer that makes feeding through side-gate loading systems smoother. Load one in your magazine tube or gate and you'll feel the difference immediately. The nickel-plated brass resists corrosion without sacrificing reloadability, and it cycles predictably through both tubular magazines and newer side-gate systems on rifles like the Henry Big Boy.
Federal tuned the velocities to exactly what you get from a lever-gun barrel. These rounds hit 1,650 feet per second, generating 768 foot-pounds of energy. The 127-grain bonded soft-point bullet is the real heart of the load. Unlike standard hunting ammunition, Federal engineered this projectile specifically for the velocity window you'll see from a rifle, not a revolver. The result is reliable expansion that penetrates cleanly without fragmenting prematurely. That matters whether you're hunting javelina, coyote, or smaller deer at woods ranges where lever guns shine.
The bonded construction holds the lead core and jacket together through brush and bone. It's not over-engineered, but it's not going to let you down either. The round chambers with zero hesitation, ejects cleanly, and you'll rarely if ever encounter a feeding hiccup. Federal specifically avoided the over-match many standard centerfire loads create in lever guns, instead focusing on the short- to mid-range engagement distances where lever-action rifles dominate.
Yes. Federal designed HammerDown ammunition specifically in partnership with Henry Repeating Arms. The case geometry and chamfered rim are optimized for smooth feeding through both tubular magazines and side-gate loading systems. Field testing shows 100-percent feeding reliability.
Absolutely. Federal engineered this projectile specifically for the velocities you get from a rifle barrel, not a handgun. The bonded construction and expansion characteristics are tuned to that 1,650 fps velocity window, delivering better terminal performance from a lever gun than standard .327 loads.
The nickel plating resists corrosion and handles weather better than standard brass, making it ideal for hunting rifles that might sit in a truck or see damp conditions. The cases are also reloadable, so you can reload them if you handload ammunition.
From a lever gun, the .327 Federal Magnum generates enough velocity and energy to handle small to medium game hunting. At typical woods distances where lever guns are used, the 127-grain HammerDown load delivers controlled expansion and solid penetration. Proper shot placement remains the most important factor.
