About .458 SOCOM Ammo

The .458 SOCOM is a large caliber rifle cartridge designed for the M4 and AR 15 platform. However, there are some bolt-action rifles or lever-action rifles in this caliber. The round was invented by Marty ter Weeme of Teppo Jutsu back in 2000 as a response to the lack of effectiveness of 5.56 ammo for members of Task Force Ranger in Operation Gothic Serpent in Somalia. Despite its original intended use, the round was never officially adopted by any military.

However, a 458 SOCOM bullet works fantastically for hunting, especially medium to large game like deer, elk, or even bears in a self-defense situation. Target shooters and plinkers also report exceptional accuracy from the 458 SOCOM cartridge, leading to the round becoming rather popular amongst recreational users.
