About .300 Win Mag Ammunition
Winchester introduced the .300 Winchester Magnum in 1963. It quickly became one of the most popular magnum cartridges in North America and has served as a military and police long-range sniper round as well.
150 grain loads are the fastest and work well on deer at long range. 165 to 180 grain bullets are the most versatile, ideal for elk and mixed game. Heavier 190 to 200 grain bullets add penetration for moose and bear.
Recoil is significantly stronger than .308 or 30-06, so a good recoil pad and practice help. For hunting, choose a bonded or controlled-expansion bullet that holds together at magnum velocities. Confirming your zero with the exact load you plan to hunt with is essential at long range.
Popular .300 Win Mag Rifles
The Remington 700, Winchester Model 70, Browning X-Bolt and Bergara B-14 are common choices in .300 Win Mag. A rifle with a 24 to 26 inch barrel gets the most out of the cartridge.
