The Federal Premium loads start with the finest primers, which are subjected to more frequent inspections for dimensional tolerances and charge weight to ensure they deliver consistent ignition for every shot. Next are the propellants, which are specially formulated to meet Federal's stringent specifications. These clean-burning powders are of the highest grades in the industry. They're consistent and reliable. The HammerDown makes your lever-gun run like never before with the industry's only ammunition truly designed for optimal cycling and overall performance from the time-tested rifle platform. Velocities are customized to produce superior ballistics and terminal performance through lever-action barrel lengths. The construction of the molecularly bonded hollow point bullets has also been adjusted for the best accuracy and expansion at those velocities. The geometry of each round case, bullet, and cartridge ensures flawless cycling through a tubular magazine and typical lever-action feeding systems.
