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. *Note- This projectile was specifically designed for use in the 300 HAMR and while it can be used in other cartridges, it may not provide optimum performance. If you wish to use this projectile for the 300 BLK, please note you will not reach optimum velocity due to case capacity constraints imposed by the bullets specifically designed geometry (shorter COAL when seated in a 300 BLK) for the 300 HAM'R.
