Born in 1963, the .300 Winchester Magnum originates from the .338 Win Mag. The new cartridge case was created from the latter by moving the shoulder 4 mm forward and by shortening the neck by 3 mm. The new cartridge sported a case neck shorter than the bullet diameter, giving it a bold and powerful look. The .300 Win Mag. is known for its extreme versatility and as such it’s a great cartridge option for hunters, target shooters, military and law enforcement departments alike.

As the .300 Win Mag. is known for its accuracy, hunters all around the world have found the cartridge to be an effective all-around choice for various types of game and hunting conditions. Most firearms manufacturers chamber for this caliber and there are numerous rifle options to choose from.
