Cor-Bon Pow rBall Features The Pow rBall ammunition line is characterized by its polymer-tipped bullets designed to ensure reliable feeding in semi-automatic firearms and to initiate expansion upon impact. The 100-grain bullet combined with a high muzzle velocity of 1 475 feet per second delivers powerful performance with increased stopping power. The +P rating of this ammunition means it s loaded to a higher internal pressure than standard ammunition resulting in higher muzzle velocity and energy. This makes the Pow rBall particularly effective for self-defense as it can deliver more force to the target.
