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 is 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 Buckshot uses copper-plated pellets to produce tight patterns and great downrange energy. It also puts more hits on target for impressive stopping power on predators, hogs and deer.
