.338 Winchester Magnum 250 Grain Barnes TSX– The .338 Winchester Magnum is a .338 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 is the caliber at which medium-bore cartridges are considered to begin. The .338 Winchester Magnum is the first choice among professional brown bear (specifically grizzly 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. The action length is the same as a .30-06 and most major rifle manufacturers in the United States chamber rifles for the cartridge including the semi-automatic Browning BAR Mk II Safari, making it a very powerful combination against charging dangerous game.
The .338 Winchester Magnum traces its heritage to the experiments conducted by Charles O’Neil, Elmer Keith and Don Hopkins with cartridges firing .333 bullets in the late 1940s.

Since its introduction in 2003, Barnes’ TSX Bullet has earned a reputation as “the perfect hunting bullet.” Now, Barnes has improved on perfection by adding a streamlined polymer tip. The new Tipped TSX features the same 100-percent copper body with multiple rings cut into the shank. It delivers the same gnat’s-eyelash accuracy and “dead right there” performance—but with an added polymer tip that boosts BC and improves long-range ballistics. The tip and a re-engineered nose cavity provide even faster expansion. Complete penetration, virtually 100-percent weight retention and four razor-sharp cutting petals that double bullet diameter means the new Tipped TSX creates more internal damage than any competing bullet. Instant expansion and perfect penetration ensures cleaner, quicker kills.
