Olympic Arms introduced a new cartridge: the .300 Olympic Super Short Magnum. According to Olympic Arms staff, the .300 OSSM is a .308 bullet in a shortened WSSM case that was designed to shoot out of a standard AR-15 platform. The result? A cartridge capable of taking any game on the North American continent that can be shot out of a handy, lightweight rifle. That is a fairly bold, and exciting, claim from OA. Introduced in conjunction with the Gamestalker rifle (see

additional information here), the .300 OSSM is specifically designed for big game hunting in North America. The cartridge is capable of launching a 150 grain, .30 caliber bullet at more than 3040 fps from a 24″ barrel. In a 22″ barrel, the same bullet is traveling at just under 3000 fps.
Currently, ammunition is available directly from Olympic Arms, but will soon be available from HSM, who helped develop the cartridge. Three loads are available now: 110 grain V-MAX (at 3400 fps), a 150 grain Speer Grand Slam (at more than 3000 fps) and a 150 grain Sierra boattail (at more than 3000 fps.) These loads should be good for taking a wide range of game in the United States and Canada. I know several people who have had a great deal of success with the Speer Grand Slam bullets, and I know that the Hornady V-MAX have worked well for me in the past for hog hunting..300 OSSM For Sale
