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.

Hunting cartridges with significant stopping power

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.

Lapua offers two new factory-loaded hunting cartridges:

.300 Win Mag. loaded with the 11,0 gram / 170 grain Naturalis bullet

.300 Win Mag. loaded with the 12,0 gram / 185 grain SP MEGA bullet.

Both cartridges offer something for every hunter. A fan favorite for many years, the traditional MEGA is a lead core, mechanically bonded, soft point hunting projectile. The third generation Lapua Naturalis bullet with its special valve design offers a completely lead-free option for that perfect mushrooming effect. With muzzle velocities that enable extremely straight flight trajectories, these rounds are an obvious choice for long range hunting or for situations that demand significant stopping power.

This cartridge offers accuracy and power well beyond 1,000 meters/yards with the Scenar projectile staying supersonic. The unique design of the 185 grain Scenar (GB432) together with the short case neck and relatively short CIP cartridge specs create an undeniably powerful combination for long range target shooting.
