Underwood Ammo 458 SOCOM 300gr Ballistic Tip Spitzer - Box or Case

The Underwood Ammo 458 SOCOM 300gr Ballistic Tip Spitzer is a premium hunting load built around the 458 SOCOM cartridge, a large-bore AR-platform round designed to deliver massive downrange energy without sacrificing standard magazine capacity. Each round pairs a 300-grain polymer-tipped boat-tail spitzer bullet with a reloadable case, engineered for flat trajectory, retained velocity, and controlled expansion on medium to large North American game.

Underwood's Ballistic Tip design uses a streamlined spitzer profile and a polymer tip to initiate expansion at the nose while the boat-tail base preserves ballistic efficiency downrange. Loaded to 1900 fps at the muzzle, this 300gr 458 SOCOM load produces approximately 2405 ft lbs of energy, serious hard-hitting performance for hogs, whitetail, mule deer, and black bear where a heavy-bullet solution is required.

The 458 SOCOM was developed specifically to give AR-pattern rifles a true large-bore option that still feeds from standard magazines, and Underwood's handloaded-grade production ammunition makes the most of that capability. The boat-tail spitzer profile delivers consistent accuracy and reliable feeding, while the polymer tip ensures rapid, uniform expansion on impact. This is the same Underwood quality shooters have come to expect, purpose-built for hunters and AR-platform enthusiasts who want to exploit the full potential of the 458 SOCOM cartridge.
