300 Win Mag – 190 gr BTHP – Federal Gold Medal Sierra MatchKing (GM300WM) – 200 Rounds

Pick up this 200 round case of Federal Gold Medal GM300WM 300 Win Mag 190 grain Sierra MatchKing BTHP ammo. Gold Medal is Federal’s match ammunition line, and this load pairs the long range reach of the 300 Winchester Magnum with one of the best known match bullets made.

The GM300WM load fires a 190 grain Sierra MatchKing boat tail hollow point at a rated 2,900 fps with 3,548 ft-lbs of muzzle energy. The bullet has a published G1 ballistic coefficient of .533, and its boat tail design helps it hold velocity and resist wind at distance. This load is built for precision and long range target shooting, F class and practical rifle matches, and load development baselines. Shooters often use it to confirm a rifle’s accuracy potential before working up handloads. It is a match load, not a hunting load; the MatchKing is designed for accuracy, not controlled expansion on game.

The 300 Winchester Magnum was introduced by Winchester in 1963 and quickly became one of the most popular magnum cartridges in North America. It is chambered in bolt action hunting rifles, long range precision rifles, and some military and law enforcement sniper rifles. Confirm your rifle is chambered for 300 Winchester Magnum before use, and do not confuse it with other 300 magnums such as the 300 WSM or 300 Weatherby, which are not interchangeable.

This case contains 10 boxes of 20 rounds each for a total of 200 rounds of Federal Gold Medal GM300WM. The ammunition is new production loaded in Federal brass with a Gold Medal match primer, and the brass is reloadable. Store the case in a cool, dry place and keep lots together so your data stays consistent from match to match. A full case of a single load gives you enough rounds to build and verify a drop chart for your rifle and then shoot matches with the same ammunition.
