The bullet is designed to penetrate to a specific depth and to fracture as the internal hydraulic pressure exceeds the hoop strength of the nose design. At the time of fracture, a massive energy spike is released as the particles break away and radiate outward from the initial trajectory path. This energy spike, and resulting temporary cavity, sends a shock wave through the animal's circulatory and nervous systems, immediately shutting down the functioning parts of these systems.
The Controlled Chaos technology differs from the Controlled Fracturing technology in that the fracturing particles are smaller, the penetration depth of the smaller particles is less, and the initial energy transfer is greater. These features make this an excellent choice for:
As with all of Underwood Ammo’s 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.

Bought a couple boxes to try out.
Was making little brass clovers on my steel plates at 100 yards to get comfortable with the load.
Decided to throw an old pork shoulder out at 250 yards, and needless to say that it nearly turned a raw pork shoulder into pulled pork.
Looks like this round is going with me hog hunting if it's going to do half the work for me :)
