The optimum hunting round has arrived.
The Xtreme Hunter (XH) was born from the incredibly popular Xtreme Defender product line. Like the XD, the Xtreme Hunter (XH) ammunition has an optimized nose flute. The difference is that weight and attained velocity have been optimized to achieve maximum penetration depth with a permanent wound cavity (PWC) that is just simply enormous. No expanding hollow point comes close to achieving anywhere near the diameter and volume of wound channel achieved by the Xtreme Hunter. Not only is the PWC over 100% larger than any other expanding bullet, terminal performance is achieved despite being shot through barriers. The solid copper body ensures that thick hide, bone, and any other barrier will have minimal effect on the Permanent Wound Channel.
This round offers:
- A permanent wound cavity (PWC) that is 2 times greater than any expanding bullet
- Reduced recoil
- CNC machined from solid copper to overcome barriers for consistent penetration
- Radial flutes that force the hydraulic energy outward due to massive pressure differentials
- Optimized frontal surface area with barrier breaking edges to that increase the force at the point of contact that effortlessly defeat even the toughest of obstacles.
- Specially designed geometry to carry the wound cavity deeper into the target than the XD, and larger than the XP.
Nickel plated casings with our new nickel plating process provides several key benefits, not limited to but including; improved feeding in all actions of firearms, enhanced corrosion resistance over traditional brass, improved cosmetics, and ease of cleanup during reloading. Nickel plated casings will not tarnish like brass during storage or when in contact with foreign materials such as leather, moisture, and other metals.
Until the development of the Ducta-Bright 7a process, nickel plating casings often limited the number of reloads as compared to raw brass. It was claimed that nickel plated brass casings embrittled the brass therefor making it less desirable for reloaders despite the ease of cleanup that nickel plating offers. In addition, ammunition engineers raising concerns of using nickel plating in very hot +P or magnum loads found that traditional nickel plating often cracked deep-drawn cases, or worse, lead to a total failure. This new process eliminates any concern, to the shooter or reloader, of hazard or ability to re-use the brass.
As with all of Underwood Ammo™ rounds, we utilize flash suppressed powder so that your vision will not be compromised if it becomes necessary to use your firearm in low light.
