Description
Federal designed HammerDown ammunition in partnership with Henry Repeating Arms to solve a real problem: getting .45 Long Colt to cycle reliably and perform consistently through lever-action feeding systems. This isn't generic ammunition repurposed for your rifle. Every component was engineered with your lever gun in mind.
Why HammerDown Was Built for Lever Guns
The case itself is different. Federal chamfered the front face of the rim on these nickel-plated brass cases, removing sharp edges that can catch and jam in tubular magazines or side-gate loading systems. That small detail makes a huge difference in the field when you need your rifle to cycle flawlessly. The case geometry also accounts for how rounds stack and feed through a lever action, something standard handgun ammunition just doesn't do.
250 Grain Bonded Hollow Point Performance
The bullet is a molecularly bonded hollow point that's been optimized specifically for the velocities this round produces from typical lever-action barrel lengths. Federal's bonding process fuses the copper jacket and lead core at the molecular level, which means the bullet holds together on impact while delivering the expansion you need for medium-size game. The hollow point sits safely in a tubular magazine without snagging, but opens up reliably when it counts.
Purpose-Built Velocities and Ballistics
This load generates 1025 feet per second with 583 foot-pounds of energy at the muzzle, measured from a 20-inch barrel. Those numbers were chosen specifically because they're what lever-action barrels deliver naturally and what terminal ballistics demand in that range. You're not getting handgun velocities with rifle expectations or vice versa. Everything works together.

Frequently Asked Questions
Will Federal HammerDown cycle reliably in my lever-action rifle?
Yes. The case geometry and chamfered rim are specifically engineered for both side-gate loading and tubular magazine systems. Federal developed this load in partnership with Henry Repeating Arms and tested it across multiple lever-action platforms to ensure flawless cycling.
Is the hollow point safe to carry in a tubular magazine?
Completely safe. The hollow point design sits securely without snagging or deforming in a tubular magazine. It won't cause the rim of one round to ignite the primer of the round in front of it, which is a real concern with some ammunition designs.
What kind of game is this ammunition suitable for?
Federal rates HammerDown for medium-size game hunting. The 250-grain bonded bullet provides the penetration and expansion needed for hogs, deer, and similar-sized animals at typical lever-action distances. The molecularly bonded construction helps retain weight while expanding reliably.
Can I reload these cases?
Yes. The nickel-plated brass cases are Boxer-primed and fully reloadable. The chamfered case design and quality nickel plating make them excellent for handloading as well.
