Features: Specially Selected Cases Cases are hand selected based on strict criteria: wall thickness uniformity internal capacity case weight and consistent wall concentricity. We get proper bullet seating consistent charges and pressures optimal velocity and repeatable accuracy. AMP (Advanced Manufacturing Process) Bullet Jackets These jackets represent a technological advancement in design tooling and manufacturing. Developed by Hornady technicians AMP Bullet Jackets feature near-zero wall thickness variation resulting in unprecedented concentricity and uniformity throughout the jacket. Powder Powder is matched carefully to each specific load for optimal pressure velocity and consistent accuracy. Primers Like the powder the primers we select are the highest quality available perfectly matched to the load.
