Brownells 75th Anniversary - A Shooting Heritage

Unrivaled Performance for Your .458 SOCOM

Known for their accuracy, precision and power, Underwood Ammo has done it again with this .458 SOCOM 300 grain Jacked Hollow Point. The Underwood Ammo Jacketed Hollow Point uses Nosler bullets, featuring a tapered copper alloy jacked that extends to the rim, ensuring good feeding from the magazine and total reliability.

The Underwood Ammo Jacketed Hollow Point comes with nickel plated cases. Underwood’s new nickel plating process brings several benefits to the table, such as better feeding, enhanced corrosion resistance, easier clean up when reloading, and of course, it just plain looks cool.
