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:

This ammo is amazingly versatile. It won't over penetrate in a household/urban environment but will definitely ruin somebody's day. That frangible shrapnel goes everywhere and that 22 size leftover bullet penetrates fairly deep. If out in the wilderness I would trust it to protect me from a mountain lion for sure.
