The .458 SOCOM is a large cartridge designed for M4, AR15, and M16 weapons, named after Special Operations COMmand Units. In many aspects, the .458 SOCOM has similar ballistic to the 45-70 Government cartridge, but has a wider range of loading and bullet configurations, from 87 gr hyper-velocity to 600 gr subsonic.
By using the standard .223/5.56mm caliber lower assembly and UNMODIFIED magazines, the .458 SOCOM Advanced Weapons System can be deployed simply by switching to a specialized upper receiver assembly that supports the large .458 SOCOM cartridge.
The RS Copper Plated Bullet is swaged from custom alloyed lead, plated to the final weight, and then Re-Struck in a carbide die. This low cost alternative to copper jacketing provides a bullet that is inexpensive, accurate, and best of all, does not lead the barrel!
