Overview of 300 Win Magnum Ammo
The .300 Winchester Magnum descended from the legendary .375 H&H cartridge, which, after many successful hunts in Africa, developed a reputation for being capable of taking every game animal on the entire continent. Following in the footsteps of its predecessor, the .300 Win Mag has a reputation for being able to take any game animal in North America.
The popularity of the .300 Win Mag surged again in the early years of the new millennium since the U.S. Army started converting its sniper rifles from .308 Winchester to the .300 WM cartridge – which can engage targets of human size at ranges as great as 1,200 meters. This distance is 50 percent farther than the reach of the .308 Winchester, a very effective sniper rifle cartridge.
Competitive shooters have also warmed up to the 300 Win Mag, as they prefer its flatter trajectory to that of the 308.
