Brownells 75th Anniversary - A Shooting Heritage

Defeat Even the Toughest Obstacles

The Underwood Ammo Xtreme Hunter .458 SOCOM round stems from the extremely sought-after Xtreme Defender line of ammo. Like its parent bullet, the Underwood Ammo Xtreme Hunter has the optimized nose flute. Weight and velocity have been tuned to generate a penetration depth and permanent wound cavity that will surprise even the most seasoned shooter.

There’s not a hollow point on the planet that comes close to the size and volume of the wound channels created by the Underwood Ammo Xtreme Hunter round. The solid copper bullet makes sure no bone, hide, tree, or barrier will slow it down.

  • Weight: 250 grains
  • Muzzle velocity: 2,000 fps
  • Muzzle energy: 2,220 ft/lbs
  • 20 rounds per box

The Underwood Ammo’s Xtreme Hunter round has an optimized frontal surface area with barrier breaking edges to increase the force at the point of contact.
