- Caliber: 308 Winchester
- Bullet Weight: 175 Grains
- Bullet Style: Lehigh Defense Controlled Chaos
- Case Type: Brass
- Suppressor Safe - This projectile is machined from solid bar stock. Expansion only occurs upon impact through hydraulic energy. (They only expand when they hit wet targets) This is not a frangible bullet produced from powdered metal.
- Muzzle Velocity: 2600 fps
- Muzzle Energy: 2627 ft lbs
- The Controlled Chaos projectile is designed to work at velocities as high as 4,200 fps and as low as 1,450 fps. This operating range makes the bullet excellent for all barrel lengths, including SBRs (short barreled riffles).
The development of the Controlled Chaos 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.
