The .270 Winchester Short Magnum is a modernization of the .270 Winchester, offering more velocity and energy for the same bullet weights fired and thus flatter trajectories. The 270 WSM, being a short action cartridge, is popular among mountainous hunters who tend to like lighter rifles and ammunition to carry around, while mostly encountering medium game at distances and angles that require fine ballistics. | Norma Tipstrike .270 WSM 140-Grain Rifle Ammo 20 Rounds
