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 Personal Defense Punch Personal loads feature a nickel-plated lead-core bullet that is propelled at extreme velocities and engineered to minimize expansion to hit critical penetration depths through short-barrel handguns. Stringent function testing also ensures the most reliable ignition, cycling, and overall performance.
