The .338 Lapua Magnum was introduced in 1989 after development by Nammo Lapua Oy in collaboration with Accuracy International and SAKO. Originally designed to give military snipers a cartridge capable of extreme-range performance, it has since earned a reputation as one of the most accurate and powerful long-distance rounds in the world. Capable of remaining supersonic past 1,300 meters, the .338 Lapua delivers heavy bullet performance with flat trajectories and tremendous terminal energy. Today it is widely used not only by armed forces but also by civilian long-range shooters, competitive marksmen, and hunters pursuing large or tough game where reach and stopping power are critical.
