Product DescriptionCorbon Pow'RBall is a high-velocity .357 Magnum self-defense load designed to deliver reliable feeding and consistent terminal performance. Each 100-grain Pow'RBall projectile features a gilding metal jacket with a lead core formed into a patented V-shaped cavity and capped with a round polymer ball that is crimped in place by the copper jacket. The polymer ball improves aerodynamics in flight and enhances feeding (including in finicky-feeding autoloaders), while also helping prevent clothing or debris from clogging the cavity. On impact, the polymer cap helps delay expansion for several inches of penetration before being displaced, allowing the V-shaped cavity to open and the bullet to expand properly.Product Highlights Polymer-ball capped Pow'RBall design promotes smooth feeding and protects the cavity from clogging Patented V-shaped cavity engineered to expand reliably after initial penetration High-velocity .357 Magnum loading rated at approximately 1,450 feet per second 100-grain defensive handgun cartridge optimized for consistent performance Convenient 20-round box for carry rotation, training, and home defense stagingSpecs Brand: Corbon Ammo Cartridge / Caliber: .357 Magnum Bullet Weight: 100 grain Bullet Type: Pow'RBall (polymer-tipped JHP design) Muzzle Velocity: 1,450 feet per second Rounds Per Box: 20 Case Material: Brass Primer Type: Boxer Country of Manufacture: Made in USA UPC: 757750357204 Manufacturer Part Number: PB357100Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
