Federal Premium Ammunition 300 Winchester Short Magnum (WSM) 180 Grain Barnes TSX 20RD

Federal Premium 300 WSM 180 Grain Barnes TSX ammunition brings proven, hard-hitting performance to your magnum rifle. The Barnes Triple-Shock X bullet has earned its reputation among serious hunters and long-range shooters for consistent accuracy and deep, reliable terminal performance on game. Built on the all-copper monolithic design that set the standard for modern hunting rounds, this load delivers what matters most when the shot counts.

The TSX's one-piece copper construction and deep hollow-point geometry produce large-diameter expansion while retaining nearly 100 percent bullet weight on impact. That combination of expansion and weight retention means deep penetration through heavy bone and muscle—critical for elk, moose, and other large game at extended ranges. The grooved bullet shank does double duty: it cuts barrel fouling that can degrade accuracy over strings of fire, and it contributes to the tight groups shooters have come to expect from this platform.

This 20-round box of Federal Premium 300 WSM ammunition is loaded to a muzzle velocity of 2980 fps with a ballistic coefficient of .453, giving you the velocity and wind-bucking performance that magnum shooters demand. Whether you're zeroing a new scope or heading into elk country this fall, Federal's reputation for consistency shot-to-shot means you can focus on making the right shot.
