The Wilson Combat 05224032CUSP features Controlled Chaos, a lead-free bullet design. Upon impact, the fluid causes the front part of the bullet to shed into multiple petals which radiate outward away from the bullet's initial trajectory. This reaction results in a significant energy spike.
The base, possessing the same diameter as the bore, continues to penetrate deeply in a straight line. The distinctive nature of this bullet separation causes a dramatic temporary and permanent wound cavity, resulting in rapid incapacitation.
The solid base of the bullet also contributes to creating additional tissue damage and often results in complete penetration of the animal.
