The K.O. gives you the safety of a quick and clean kill and offers 58 % more frontal area, resulting in massive energy transfer. Deep penetration, expansion up to .9", you name it, the K.O. got it. It features Brenneke's improved Foster design that gives you great knockdown power. Terrific accuracy. Its wad generates higher velocity, more power, and a flatter trajectory. The K.O. utilizes a lead point with ribs that point to the right to ensure smooth choke passage and patented rear slides into the point after the impact.
