The .458 SOCOM is a relatively large round designed for a specialized upper receiver that can be mounted on any M4 or M16 style rifle. The 300-grain (19 g) round offers a muzzle velocity 1,900 ft/s (580 m/s) and an extraordinary 2,405 ft·lbf (3,261 J). ^[1] In many respects, it is similar to the venerable .45-70 Government.

[edit] History

Inspired by the lack of stopping power offered by the 5.56 NATO cartridge used in the M4 and the M16, the .458 SOCOM came about from informal discussion of members of the Special Forces community, specifically Delta Force's experience that multiple shots were required to neutralize members of the opposing force in Mogadishu during Operation Gothic Serpent. Marty ter Weeme, founder of Teppo Jutsu LLC, went to work to develop a new cartridge that would deliver far more energy from short barrels at relatively short distances.^[2]
