.270 Winchester Short Magnum 130 grain Barnes TTSX~ The 270 Winchester Short Magnum or 270 WSM is a short, unbelted, magnum cartridge created by necking down the .300 Winchester Short Magnum and fitting it with a .277 caliber bullet. The correct name for the cartridge, as listed by the Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI), is 270 WSM, without a decimal point. When it was introduced, the 300 WSM sported a new case that showed a lot of promise for uses in other calibers. In 2002 Winchester introduced new cartridges in its Winchester Short Magnum family, including the 7 mm WSM and 270 WSM. This new .270 cartridge was the third commercial .270 ever produced, and the first one in 60 years.
The 270 WSM is an improvement over the older 270 Winchester providing higher velocity with bullets of the same weight, and thus a flatter trajectory and more energy. Velocities tend to be about 250 ft/s (76 m/s) faster, in a cartridge that is shorter and can therefore be used in a shorter action for a more compact rifle if desired. The 270 WSM comes quite close in performance to that of the legendary .270 Weatherby Magnum. Except that the WSM is chambered in a short action and usually sports a 22″ to 24″ barrel where the Weatherby is usually chambered in rifles with a 26″ barrel.

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.
