Wilson Combat 05308152CUSP: Controlled Chaos lead free bullets 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.
