New .300 Winchester Magnum Lapua Cartridges

    During my recent evaluations of various thermal front attachments, I shot some .300 Winchester Magnum from various bolt-action rifles. If you have a rifle chambered in this caliber, or thinking about getting one, there are now three new choices from Lapua. There are two new hunting cartridges and one focused for long range accuracy. For instance, the Lapua soft-point Mega bullet weighs 12,0 gram / 185 grain,  which makes it very suitable for big game hunters. The Naturalis is a lead-free option, as it’s made out of copper.

    Here’s the news release from Lapua:

    New .300 Winchester Magnum cartridges for hunters and target shooters

    For 2021, Lapua offers three new cartridges for .300 Winchester Magnum. 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

    With the new .300 Win Mag. Lapua case we now also offer two new factory-loaded hunting cartridges:

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

    .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 with that perfect mushrooming effect.

    Long range target accuracy with Lapua Scenar

    For the demanding target shooters, long range enthusiasts and tactical units, Lapua offers the perfect cartridge option:

    the .300 Win Mag. with the 12,0 g / 185 gr OTM Scenar bullet.

    This round offers accuracy and power well beyond 1,000 meters/yards with the Scenar projectile staying supersonic.

    All three Lapua cartridges will be hitting the markets in the spring of 2021.
