Cor-Bon Self Defense .458 SOCOM 300gr JHP Ammo, 20-Round Box

Cor-Bon Self Defense .458 SOCOM 300-grain jacketed hollow point ammunition (brand part no. SD458300CMMG) brings Cor-Bon’s high-velocity philosophy to one of the hardest-hitting AR-platform cartridges on the market. Cor-Bon built its reputation on pushing jacketed hollow points harder than the competition, and this .458 SOCOM load is no exception, using an exclusively designed JHP bullet that Cor-Bon rates for consistent expansion at roughly twice the bullet’s original diameter in ballistic gelatin testing. That combination of heavy bullet weight and high velocity gives the .458 SOCOM serious stopping power for home defense or hunting, with penetration depths that stay in a controlled, effective range. For shooters who run a .458 SOCOM upper and want a load built around raw energy transfer, this is rifle ammunition engineered for exactly that.
