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 TruBall Deep Penetrator rifled slug gives it the power to smash through even the toughest tissue. The TruBall system locks the components together, centering and pushing the lead slug out of the barrel, for groups as tight as 1.4 inch at 50 yards.
