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. Punch draws from Federal Ammunition's decades of experience designing the world's finest defensive handgun loads. The bullet's skived jacket and soft lead core produce the best expansion and penetration, while its nickel-plated brass and sealed primer deliver the reliable feeding and ignition you need to protect yourself.
