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 Marksmen and by some branches of the US Military for use by their snipers. Maximum effective range is generally accepted to be 1200 yards (about 1100 meters) with ammunition incorporating low drag projectiles, while accuracy well below 1 minute-of-angle out to 1000 yards (about 910 meters) 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). Game is any animal hunted for food or not normally domesticated (such as venison). ... “Hunter” redirects here. ...
