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. Handgun hunters leave nothing to chance when it comes to bullet choice. That's why Federal offers the robust, proven Swift A-Frame. High weight retention and controlled expansion, regardless of distance, make these rounds ideal for big game.
