The Federal Premium Barnes TSX .300 WSM (180 gr) is built for serious big-game hunters who demand tight groups at distance and uncompromising terminal performance. The Barnes Triple-Shock X (TSX) all-copper hollow point delivers consistent, large-diameter expansion while its monolithic, one-piece copper design retains nearly 100% of its weight on impact for deep penetration through heavy bone and muscle. A grooved bullet shank minimizes barrel fouling and enhances accuracy, and a deep hollow-point tip initiates reliable expansion across a wide velocity window. At a muzzle velocity of ~2980 fps, this load offers flat trajectories and hard-hitting energy for elk, moose, and other large game.
