The Premium Die Set for Handgun Cartridges is a precision-engineered three-die set, designed to elevate the reloading process with efficiency and accuracy. This set includes the NxGEN Carbide Sizing Die, a distinctive Special Expander Die and a Premium Seating Die with a standard Bullet Seating Micrometer. Each die is crafted with a large entry taper and radius, ensuring easy case entry and enabling high-volume production. The Special Expander Die boasts a unique design that performs four distinct functions. It begins with a smooth entry radius, followed by an expanding diameter that creates the perfect press fit for the bullets. The upper section of the expander incorporates a concentric ring, which slightly enlarges the case mouth beyond the bullet diameter to improve bullet alignment. The final taper allows for a "bellmouth" effect on the case mouth when needed, particularly useful when reloading lead bullets. This innovative design ensures optimal bullet seating, precision and consistent reloading performance.
