Controlled Chaos bullets offer the best of both. Once the fluid is impacted, it shed the front portion of the bullet into multiple petals that radiate outward away from the bullet's 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 cavities created by this bullet separation is dramatically resulting in quick incapacitation. The solid base creates additional tissue damage and often results in full penetration of the animal. The Controlled Chaos doesn't expand or fragment when it impacts hard barriers like drywall, only when it impacts fluid, where it expands, fractures, and does its devastation.
