Description

SBR Ammunition 458 SOCOM 250 Grain (aka: 11.5x40mm RB) is a large caliber cartridge designed for use on the AR15/M4 platform. It was developed by Marty ter Weeme, founder of Teppo Jutsu LLC in 2000. The impetus was an informal (“beer and barbeque”) discussion with a senior member of the US special operations community regarding the apparent lack of effectiveness of the 5.56x45mm rifle cartridge in a recent conflict. In particular, the reports from members of Task Force Ranger in Mogadishu, Somalia as part of Operation Gothic Serpent that multiple shots were required to neutralize members of the opposing force led to the request to develop a new cartridge that would deliver far more energy from short barrels at relatively short distances.

After the design was completed, Tony Rumore of Tromix Corp in Broken Arrow, OK was contacted to build the first prototype. Based on the favorable reviews, commercial production was started and the initial rifles were produced by Tromix. Marty contacted me, Buddy Singleton, at Southern Ballistic Research, LLC (SBR) in Brunswick, GA, and asked me to develop factory loadedSBR Ammunition 458 SOCOM 250 Grain
