The .338 Winchester Magnum is a rifle cartridge of .338 inch (8.6 mm) caliber, belted, rimless and bottlenecked, introduced in 1958 by Winchester Repeating Arms. It is based on the .375 H&H Magnum case, shortened to 2.500 inches and blown out, and shares its case design with the .264 Winchester Magnum and .458 Winchester Magnum released the same year. Its roots lie in the late 1940s experiments of Charles O'Neil, Elmer Keith and Don Hopkins with the .333 OKH and .334 OKH. The source describes it as the most popular medium-bore cartridge in North America, favoured for elk, moose and dangerous game such as great bears. SAAMI recommends a maximum average pressure of 64,000 psi, and the CIP applies a limit of 4,300 bar.
