Product DescriptionCorbon Pow'RBall self-defense ammunition is engineered to deliver reliable feeding and consistent terminal performance in semi-automatic pistols. Each cartridge features a gilding metal jacket with a patented V-shaped lead core, capped with a round polymer ball that helps create a smooth, full-metal-jacket-like profile for enhanced feeding. In flight, the polymer ball improves aerodynamics; on impact, it helps delay expansion for initial penetration before the cavity is exposed to promote full, proper expansion.Product Highlights Pow'RBall polymer-ball capped design helps promote reliable feeding in auto pistols Patented V-shaped lead core designed to support controlled, full expansion .45 ACP +P performance rated at 1,225 feet per second (fps) New-production, non-corrosive, boxer-primed ammunition in reloadable brass cases 20-round box ideal for personal protection and defensive carry rotationSpecs Brand: Corbon Ammo Cartridge: .45 ACP +P Bullet Weight: 165 grains Bullet Type/Style: Pow'RBall, polymer-tipped / polymer-ball capped Muzzle Velocity: 1,225 feet per second (fps) Muzzle Energy: 550 foot-pounds (ft-lbs) Case Type: Brass Primer: Boxer Corrosive: No Reloadable: Yes Rounds per Box: 20 Country of Manufacture: Made in USA UPC: 757750451704 Manufacturer Part Number: PB45165Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
