At the heart of the Superformance Shotgun slug is the MonoFlex projectile topped with the Hornady exclusive Flex Tip design that works as a catalyst for uniform expansion, even at low velocities. The MonoFlex won’t separate, and retains 95% of its original weight. Fueled by Hornady’s specially blended propellants, the Superformance Shotgun Slug is built to deliver maximum velocity for flatter trajectories and enhanced terminal performance.
