The .338 Lapua Magnum (8.six×70 mm or 8.58×70 mm) can be a rimless, bottlenecked, centerfire rifle cartridge. It was created in the course of the nineteen eighties to be a high-run, long-range cartridge for military snipers. As a result of its use inside the War in Afghanistan as well as the Iraq War, the cartridge is becoming broadly obtainable.
