Lehigh Defense Controlled Chaos Bullets 270 Caliber (277 Diameter) 112 Grain Fracturing Copper Hollow Point Boat Tail Lead-Free


Category: Product ID: 7224


The development of the Controlled Chaos technology was the result of an animal control agency’s request for a no lead .243 bullet that would provide extensive wound trauma with little 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 with shot placement at or near the central nervous system. The agency had tried copper matrix frangible rounds and found the penetration depth and particle size were less than what was require 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 of these systems.


Since the development of the .243 bullet, Lehigh has taken this design to other calibers.  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 bullet choice for varmint hunting, animal culling, fur hunting, and personal defense.


The Copper Version of the Controlled Chaos Bullet is designed to work at velocities as high as 4,200 fps to as low as 1,500 fps.  This operating range makes the bullet excellent for Full Length Barrels, SBR’s and AR Pistols.


Suppressor Safe — The projectile is machined from solid bar stock.  Expansion only occurs upon impact through hydraulic energy.  (They only expand when they hit “wet.”)  This is not a frangible bullet produced from powdered metal.
