458 SOCOM with Explosive Melons!

The .458 SOCOM [11.63 x 40 mm] is a moderately large round designed for a specialized upper receiver that can be mounted on any AR-15 pattern lower receiver. Inspired by the lack of power offered by the 5.56 NATO cartridge used in the M4 carbine and the M16 rifle, the .458 SOCOM came about from informal discussion of members of the special operations community, specifically Task Force Ranger's experience that multiple shots were required to neutralize members of the opposing force in Mogadishu during Operation Gothic Serpent. Marty ter Weeme of Teppo Jutsu designed the cartridge in 2000 and Tony Rumore of Tromix was contracted to build the first .458 SOCOM rifle in February 2001. Tony Rumore fired the very first round of .458 SOCOM ammunition in the Tromix shop located in Broken Arrow, Oklahoma on February 16, 2001, at 8:30pm.
