Product DescriptionCorbon Pow'RBall 9mm Luger +P ammunition is designed for dependable performance in defensive semi-auto pistols, combining reliable feeding with controlled terminal performance. 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 that is crimped in place by the copper jacket. In flight, the polymer ball helps streamline airflow for improved ballistics; on impact, it helps delay expansion to allow initial penetration before exposing the V-shaped cavity for proper expansion. The polymer cap also helps protect the hollow point cavity from clogging when passing through clothing or other barriers.Product Highlights Pow'RBall polymer-ball capped design helps enhance feeding reliability in auto pistols +P 9mm Luger loading for increased velocity and defensive performance 100 grain polymer-tipped Pow'RBall projectile engineered for controlled expansion Rated muzzle velocity of 1,475 feet per second 20 rounds per box (20/500 case configuration)Specs Brand: Corbon Ammo Model/Line: Pow'RBall Caliber: 9mm Luger (9x19) Pressure: +P Bullet Weight: 100 grain Bullet Type: Pow'RBall (Polymer-Tipped) Muzzle Velocity: 1,475 feet per second Casing Material: Brass Rounds per Box: 20 Boxes per Case: 25 (500 rounds per case) Country of Manufacture: USA Manufacturer Part Number: PB9100 UPC: 757750900707Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
