Hornady creates the ultimate competition projectile with the HAP (Hornady Action Pistol) Bullet. They take much of their design from Hornady’s XTP bullet, but have been further refined for greater accuracy. The HAP removes the jacket serrations found on the XTP bullets, creating a much more streamlined, balanced profile. The jacket on the HAP bullets features industry leading concentricity, and utilizes a protected nose that aids in consistent, reliable feeding in semiautomatic pistols. In addition, the core of the HAP bullet is cold swaged from pure lead to deliver consistency, balance and stability in flight. It delivers pinpoint accuracy with every shot.
