.300 Win Mag Ammunition

Also known as: 300 win mag, 300 Win, 300 Winchester Magnum, .300 Winchester Magnum

The .300 Winchester Magnum is a rifle cartridge released in 1963 as an addition to the Magnum cartridge family. It was built to work with standard length action and has foundational similarities to the .375 H&H Magnum. With this basic design, it has been necked down to receive a 30 caliber bullet. Because of its versatility, law enforcement, military personnel, target shooters, and hunters use the 300 Win Mag. It is still the most popular 30 caliber magnum used by American hunters today even though the .300 Rem Ultra Mag and the .300 Weatherby Mag can surpass its performance.
