For 9mm, .40 Smith & Wesson, .45 caliber, and others, Hornady HAP Handgun Bullets are an excellent and economical choice. These bullets are engineered to perfection and commonly used by competitive shooters due to their incredible balance, consistency, and flight stability. However, the unrivaled accuracy is one of their most important characteristics \. The HAP bullet is not designed with a cannelure and folds to help with expansion and increase terminal performance, but it does have a special pure lead core within a copper jacket design that prevents gun jams and protects the nose for seamless feeding.
