270 WSM (Winchester Short Magnum)




SKU: 53671 Categories: , Tag:


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 resulting in a more compact rifle if desired.The .270 WSM is the only cartridge of the WSM family that produces notable ballistic gains over other existing cartridges. The .300 WSM closely mimics the long-popular .300 Winchester Magnum, while the 7mm WSM matches performance of the 7mm Remington Magnum in similar barrel lengths. The .325 WSM is in a league of its own in North America as the 8 mm caliber has not become commonplace.  The .270 WSM comes quite close in performance to that of the legendary .270 Weatherby Magnum, with notable differences being that the .270 WSM is chambered in a short action and normally utilizes a 24″ barrel whereas the older Weatherby cartridge utilizes a long action and is most commonly paired with a 26″ barrel.
