300 WEATHERBY MAG

300 Weatherby ammunition is a very powerful round, utilizing a 30 caliber bullet. The 300 Weatherby Magnum uses the plentiful and popular 300 H&H Magnum case as its parent case. Roy Weatherby, the famed gun and ammo designer, designed the round in 1944.

The 300 Weatherby Mag is Weatherby’s most popular round by far. Despite nearly a century of history, the round is still one of the more powerful 30-cal cartridges available to American civilian shooters. Because of that power, the 300 Weatherby Magnum is one of the more popular rounds with big game hunters, which has led to increased availability around the world.

300 Weatherby Magnum ammunition comes in a wide variety of loads, from lighter, more moderate rounds, to heavier, more powerful rounds. The lighter loads are typically a 150 grain round fired at 3,540 feet per second, and heavier loads are typically 220 grains at 2,845 feet per second.

    Great price on high quality ammo
    Jim on 20rds - 300 Weatherby Mag. 150gr. Spire Point Ammo
  • ☆☆☆☆☆
    I have used this ammunition for years on large game (elk) and smaller game (antelope) in New Mexico. When you use this ammo on a short shot, 100 yards or so, it seems to pass through before it has a chance to expand. On a long shot, say, 350-400 yards or more, it does expand and has great knock down power at the greater distances. Tell Turkey Surprise to get out of his tree stand and let his deer run a ways before he locks in on it!! He will still knock it down if he can hit it a 400+ yards

    Excellent accuracy, but does not expand on deer. Although I've got no expansion, every deer shot has dropped instantly.
