The development of this technology was the result of an animal control agency's request for a lead-free bullet that would provide an extensive wound trauma with minimal pass-through energy. Basically, the idea was to burst the bullet into numerous particles at a predetermined depth creating many wounds and a large temporary cavity at or near the central nervous system with proper shot placement. The agency had tried copper matrix frangible projectiles and found the penetration depth and particle size were less than what was required for proper terminal performance. 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.
