.338 Lapua Magnum is a rimless, bottlenecked, centerfire rifle cartridge. It was developed during the 1980s as a high-powered, long-range cartridge for military snipers. It was used in the Afghanistan War and the Iraq War. As a result of this, it became more widely available.
In 1983, Research Armament Industries in the United States began the development of a new, long-range sniper cartridge capable of firing a 16.2-gram, 0.338-inch diameter bullet at 914 meters per second that could lethally penetrate five layers of military body armor at 1,000 m.
The loaded cartridge is 14.93 mm (0.588 in) in diameter (rim) and 93.5 mm (3.68 in) long. It can penetrate better-than-standard military body armor at ranges up to 1,000 meters and has a maximum effective range of about 1,750 meters with C.I.P. conform ammunition at sea level conditions.
