.300 Winchester Magnum (known as .300 Win Mag or in metric countries as 7.62 × 67 mm) is a popular magnum rifle cartridge that was introduced by Winchester Repeating Arms Company in 1963 as a member of the family of Winchester Magnum cartridges. It is an accurate, long-range round with a relatively flat trajectory.

Performance

The .300 Win Mag is a cartridge for large game hunting and long range shooting. It sees use in long range benchrest competition and has been adopted by Law Enforcement Marksman and by a few specific branches of the US Military for use by their snipers. Maximum effective range is generally accepted to be 1210 yards (1097 m) with ammunition incorporating low drag projectiles. Sub 1 minute-of-angle (MOA) accuracy out to 1000 yards (914 m) is not unusual in precision built rifles firing match grade ammunition. Velocity with a 180 grain projectile at max powder charge and 24" barrel is 2975 ft/s ±25 ft/s (907m/s ±7.6m/s).

Recoil from the .300 Win Mag is high, much higher than the .30-06 Springfield. Remington has made low-recoil rounds called "Managed-Recoil" available, that kick less and provide performance similar to the .300 Savage.

Other information

Like the other members of Winchester Magnum family, the cartridge is based on a shortened version of the H&H casing.2002, "Lyman Reloading Handbook, 48th Edition"]

The .300 Win Mag remains the most popular .30 caliber magnum with American hunters, despite being eclipsed in performance by the more powerful .300 Weatherby Magnum and newer .300 Remington Ultra Magnum. It is a popular selection for hunting Elk, because it delivers better longer range performance than non-magnum .30 caliber cartridges.

The .300 Winchester Magnum is fired by an uncommon sniper rifle manufactured by Walther, the WA 2000.
