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 HEVI-Bismuth hits both upland birds and waterfowl with the power of 9.6 g/cc density pellets. Sourced from Federal's partners at HEVI-Shot, HEVI-Bismuth shot is 22 percent denser than steel, delivering more lethal energy downrange. Launched by the FLITECONTROL FLEX wad, bismuth pellets pattern consistently, and their metallic properties make them safe in both modern and classic shotguns.
