Federal Premium 300 Winchester Magnum 165 Grain Barnes TSX Ammunition

Federal Premium 300 Winchester Magnum ammunition features primers subjected to frequent inspections for dimensional tolerances and charge weight, ensuring consistent ignition shot after shot. The propellants are specially formulated to meet Federal’s stringent specifications, utilizing clean-burning powders of the highest grades available. Precision-built cases are nickel-plated brass that resists corrosion and promotes smooth extraction even in extreme conditions. Each round is loaded with a Barnes Triple-Shock X bullet—an all-copper hollow point that delivers tight groups at long range with consistent, large-diameter expansion. The monolithic design retains nearly 100 percent of its weight on impact for deep penetration, while its grooved shank minimizes barrel fouling and improves accuracy. This 165 grain load combines Federal’s quality control with proven Barnes bullet technology for dependable performance.
