.300 Win Mag



The .300 Winchester Magnum has been a staple within the firearms industry, widely used by hunters, target shooters, military and law enforcement agencies around the globe since its development in the early 60’s. It is still used for competitive target shooting, hunting, and Mil/LE platforms to-date. It delivers excellent long range performance with a wide range of bullet weights from 165 to 200 grains and more. The .300 Winchester Magnum has a great reputation as a .30 caliber magnum hunting cartridge in Europe and North America. Lapua’s .300 Win. Mag case will be a great addition to our line, especially with the huge bullet selection available for sport shooting and hunting for this caliber and all major rifle manufacturers chamber their rifles for it.

The .300 Win Mag case will be available for home loaders in spring of 2021. For availability in your country, please check with your distributor.
