The .338 Winchester Magnum is a .338 in (8.6 mm) caliber, belted, rimless, bottlenecked cartridge introduced in 1958 by Winchester Repeating Arms. It is based on the blown-out, shortened .375 H&H Magnum. The .338 in (8.6 mm) is the caliber at which medium-bore cartridges are considered to begin.

The .338 Winchester Magnum ammo is based on the .375 H&H Magnum, which was shortened to 2.500 in (63.5 mm), blown out, and necked down to hold a .338 in (8.6 mm) bullet.

The .338 Winchester Magnum rifles are the first choice among professional brown bear guides in Alaska to back up clients where a powerful stopping caliber is required on charging bears. It is also the most popular medium-bore cartridge in North America and has the most widely available choice in rifles among medium bore rifles.
