Federal Premium 308 Winchester Barnes TSX ammunition combines a 165-grain all-copper hollow point with Federal’s match-grade brass and primers to deliver a hunting round engineered for terminal performance without lead. The Barnes Triple-Shock X bullet features four cutting petals that expand reliably across a wide velocity window, retain near-100% of original weight, and penetrate deep on quartering shots. At 2700 fps muzzle velocity and 2671 ft-lbs of energy, this load bridges the gap between flat trajectory and controlled expansion — effective on deer, hogs, and black bear from 50 to 300 yards. Each 20-round box ships with boxer-primed, reloadable brass cases.
Built for the Box
Federal Premium sources Barnes Triple-Shock X projectiles — a solid copper hollow point designed to shed no core material and maintain structural integrity through hide, bone, and tissue. The 165-grain weight balances sectional density and velocity, making it suitable for .308-length magazines in bolt guns and semi-autos. Federal brass is drawn to tight tolerances and annealed for consistency; boxer primers ignite cleanly in all weather. Because the bullet contains no lead, this load meets California lead-free hunting requirements under the Condor Preservation Act and complies with expanding regulations in other Western states. You can hunt federal lands, state WMAs, and private property under lead-free mandates without changing your rifle or zero.

This load fits standard SAAMI 308 Winchester chambers and feeds from AICS, PMAG, and proprietary hunting rifle magazines. Expect point-of-impact shift if transitioning from lead-core loads; copper bullets of the same weight are longer and may contact the rifling differently.
