What is 458 socom?

The .458 SOCOM is a large-bore cartridge designed for use in the AR-15 platform. Its primary purpose is to provide significantly increased stopping power at short to medium ranges compared to the standard 5.56 NATO cartridge.

• Origin and Development: The cartridge was developed by Marty ter Weeme of Teppo Jutsu LLC in 2000, and officially released in 2001, in response to a request from US Special Operations Command (SOCOM) for a cartridge with greater terminal ballistics for use in close quarters combat.

• Cartridge Specifications: The .458 SOCOM uses a rebated rim, meaning the rim is smaller than the cartridge body. The rim diameter is the same as the 5.56 NATO, which allows it to function in a standard AR-15 bolt. The cartridge is designed to use .458-inch diameter bullets, typically weighing between 250 and 600 grains.

• AR-15 Compatibility: A significant advantage of the .458 SOCOM is its compatibility with standard AR-15 lowers. The conversion typically requires only a new upper receiver assembly, including the barrel, bolt, and magazine. Magazines are often modified 5.56 magazines, with a reduced capacity due to the larger cartridge size.

• Performance: The .458 SOCOM offers excellent stopping power, making it suitable for hunting large game, personal defense, and law enforcement applications. It is effective at ranges up to approximately 250 yards, with a significant drop in velocity and energy beyond that range. The cartridge operates at relatively low pressures compared to other AR-15 cartridges, contributing to its reliability.
