The .338 Lapua Magnum (eight.six×70 mm or 8.58×70 mm) can be a rimless, bottlenecked, centerfire rifle cartridge. It had been designed in the nineteen eighties being a large-powered, long-vary cartridge for armed service snipers. Resulting from its use while in the War in Afghanistan as well as the Iraq War, the cartridge is now widely out there.
