.458 SOCOM The .458 SOCOM cartridge was developed in order to provide superior stopping power for AR-15 based weapon systems, in view of the questionable effectiveness of the 5.56 mm round in recent conflicts. A new cartridge in .458 calibre was selected as this not only offers considerable stopping power but also offers the user a vast choice of commercially available bullets, ranging from 300 gr. (19.4g) HP and Spitzers, 405 gr. (26.2g) FN, up to 500 gr. (32.4g) Solids and Tungsten Core RN. A case of the same diameter as the .50AE that would completely fill the AR-15 magazine seemed the right choice, but the rim needed further reducing to avoid much work to the bolt lugs. The use of an even more drastically rebated rim seemed the solution, and the 0.473” (12.0 mm) diameter rim employed by the .308 and .30-06 based cartridges was chosen, as this would allow easy retrofit of bolt action rifles in this calibre. Looks like a new bolt is needed. |
