The best predicted firing range for the .338 Lapua Magnum cartridge is up to 1,500 m.

History
In 1983, the U.S. Department of Defense set the task of developing a new cartridge for sniper shooting. Jerry Haskins of Research Armament Industries (RAI), Jim Bell, and Boots Obermeyer developed an 8.6 mm cartridge based on the .416 Rigby cartridge, but he found that the cartridge was deformed due to the high pressure of the powder gases. The Finnish company Lapua (a division of the Norwegian company Nammo [2] ) solved this problem by creating an almost new reinforced cartridge case, and in 1987 began commercial production of cartridges under the designation .338 Lapua Magnum. Currently, the production of .338 Lapua Magnum is also carried out by the Swedish company Norma Precision [1] , Czech Sellier & Bellot [3] , Ulyanovsk Cartridge Plant [4] , Novosibirsk Cartridge Plant [5] (Russia).
