.300 Win Mag Ammo

Introduced by Winchester® in 1963, the .300 Winchester Magnum is a popular big game hunting, tactical, and target cartridge, built around a belted and bottlenecked design. The .300 Win Mag remains the most popular .30 caliber magnum with American hunters, despite being surpassed in performance by the more powerful .300 and .30-378 Weatherby Magnums and the newer .300 Remington Ultra Magnum. Thanks to the cartridge’s ability to reach long distances beyond 1,000 yards, military and law enforcement agencies across the globe quickly adopted the cartridge for long-range sniping and marksmanship applications. In fact, in March 2013, the DOD conducted tests against ballistics gelatin, light material barriers, and other targets to determine the projectile's ability to perforate targets. The results showed that the .300 Win Mag cartridge, under proper conditions, could easily strike and drop targets out to 1,200 meters (1,312 yards).
