Shooters were so impressed with Underwood Ammo’s Xtreme Defender product line that hunters demanded a similar round specially tailored for them. Well, Underwood Ammo answered with their new Xtreme Hunter line. With an optimized nose flute, the weight and velocity have been carefully tweaked to achieve max penetration and create a huge permanent wound cavity.

With reduced recoil, the Underwood Ammo Xtreme Hunter’s specially designed nose CNC machined right into the solid copper slug, busts straight through barriers like they’re not even there.  All that frontal surface area hits the target hard, too.
