The Federal HammerDown 22HAM rimfire load is a 22LR 40 gr copper-plated hollow point engineered to bring centerfire-style terminal performance to lever-action rimfire rifles, and as a hunter and range officer I recommend it for small-game hunting and brush country shooting where controlled expansion and reliable feeding matter. The HammerDown series tunes muzzle velocity to about 1200 fps for a flat, consistent trajectory while the nickel-plated brass offers corrosion resistance and smooth feeding from tubular magazines and typical lever-action feeding systems, so youll spend more time on target and less at the loading gate. In the field this cartridge delivers dependable expansion on game like rabbit and varmints while maintaining the cycling reliability needed for quick follow-up shots in brass-framed and polymer-framed rimfire lever guns. For shooters who favor hollow-point performance in a rimfire platform, Federals HammerDown 22LR rounds balance accuracy, feeding consistency, and terminal effectiveness, making them a sound choice for hunting, pest control, and lever-action shooting disciplines where ballistics and reliable functioning are required.
