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.

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:

• varmint hunting
• animal culling
• fur hunting and
• personal defense.

Nickel-plated brass casings our 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.

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.
