This cartridge, however, the .458 SOCOM (.458 Special Operations Command) was reportedly given birth over a barbeque and some cold brew. It was at an informal gathering of special ops personnel, specifically Task Force Ranger, when the subject of stopping power came up. It seems it took multiple hits to permanently take the opposition “out of the game” in Mogadishu, Somalia. The consensus was a one-shot stop would sure be nice. Marty ter Weeme, founder of a company called Teppo Jutsu, L.L.C., went to work. In 2000 a sledgehammer cartridge that would launch 250- to 600-grain .45 caliber bullets from a standard size AR-15 with a proper barrel and chamber was born — enter the .458 SOCOM.
