Controlled Chaos bullets offer the best of both. Once fluid is impacted, they shed the front portion of the bullet into multiple petals that radiate outward away from the bullets initial trajectory path resulting in a massive energy spike. The bore diameter base of the bullet continues and penetrates deeply in a straight line. Both the temporary and permanent wound cavity created by this bullet separation is dramatic resulting in quick incapacitation. The solid base creates additional tissue damage and often results in full penetration of the animal. The Controlled Chaos bullet doesnt expand or fragment when it impacts hard barriers like drywall, only when it impacts fluid, where it expands, fractures, and does its devastation.
