The .458 SOCOM (Special Operations Command) is a powerful, large-bore cartridge designed for the AR-15 platform. Developed in the early 2000s by Marty ter Weeme of Teppo Jutsu LLC, it was intended to provide superior stopping power and terminal ballistics for special operations and military contexts, particularly in close-quarters combat.
The cartridge features a .458-inch diameter bullet and is compatible with standard AR-15 lower receivers, although it requires a specialized upper receiver, barrel, and magazine. The .458 SOCOM can fire bullets ranging from around 250 to 600 grains, offering significant flexibility in terms of performance and application.
This cartridge is noted for its capability to deliver substantial energy on target, making it effective for hunting large game, including deer, hogs, and even some African game animals. It's also utilized for tactical applications where a high-stopping power is critical, although its use is less common in conventional military or law enforcement scenarios.
Recoil is notably higher than standard AR-15 cartridges like the 5.56 NATO, but it remains manageable for experienced shooters.
