.300 Winchester Short Magnum Ammo

300 Winchester Short Magnum Ammo (generally called 300 WSM) is a shorter, fatter, round that was designed to match the ballistics of the old, longer 300 Winchester Magnum. It has 10% less powder, and can be fired through shorter, and lighter rifles. The 300 WSM is an efficient cartridge for throwing 150-180 grain .308 bullets at over 3,000 feet per second. It can kill any big game from elk, grizzlies, and moose. So don't worry about dropping your whitetail. While not as "hot" a round as the standard .300 Win Mag, the .300 WSM is still very capable for all your target shooting and hunting needs. Look through our options and see what fits your needs!
