Underwood Controlled Chaos Technology
The Controlled Chaos round represents a significant advancement in terminal ballistics design. Developed in collaboration with professional animal control agencies, this ammunition delivers precisely controlled fragmentation at a predetermined depth.
How It Works
The bullet is engineered to penetrate to a specific depth before fracturing. As internal hydraulic pressure exceeds the nose design's hoop strength, the projectile breaks into multiple particles that radiate outward from the initial trajectory. This creates:
- A massive energy spike upon fracture
- Extensive temporary cavity formation
- Shock wave transmission through circulatory and nervous systems
- Immediate incapacitation with proper shot placement
Superior Design Features
Controlled Chaos vs. Controlled Fracturing: This ammunition uses smaller fracturing particles with reduced penetration depth of individual fragments, but delivers greater initial energy transfer—making it ideal for varmint hunting, animal control, fur hunting, and personal defense applications.
Nickel-Plated Brass Casings: Our proprietary nickel-plating process provides:
- Enhanced feeding reliability across all firearm actions
- Superior corrosion resistance compared to traditional brass
- Improved appearance and easier reloading cleanup
- Resistance to tarnishing during storage or contact with moisture and other materials
Flash-Suppressed Powder: Preserves your low-light vision if defensive use becomes necessary.
