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. Lastly, the casing. The precision-built cases in most centerfire Premium loads feature nickel-plated brass that defeats corrosion and aids in sleek, smooth extraction in even the most extreme conditions.The Barnes Triple-Shock X is a proven all-copper hollow point that groups tightly at long range and delivers consistent, large-diameter expansion. The monolithic design retains nearly 100 percent of its weight on impact to penetrate deep, and its grooved shank minimizes barrel fouling and improves accuracy.
