Product DescriptionCorBon Pow'RBall 10mm Auto ammunition is engineered for reliable feeding and consistent expansion in semi-auto pistols. The Pow'RBall projectile uses a gilding metal jacket with a lead core formed into a patented V-shaped cavity, capped with a round polymer ball. This polymer cap improves aerodynamics and helps prevent the hollow point from clogging with clothing or other barriers. On impact, the polymer ball helps delay expansion briefly for initial penetration before being displaced to expose the V-shaped cavity for full, controlled expansion.Product Highlights Pow'RBall polymer-capped projectile enhances feeding reliability in auto-loading pistols.
