The Premium Die Set for Handgun Cartridges is a top-tier three-die set designed to deliver precise and efficient reloading. Included in the set are the NxGEN Carbide Sizing Die, a specialized 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 optimizing production efficiency. The Special Expander Die features a unique design that performs four critical functions to enhance bullet seating. The die begins with a smooth entry radius and progresses to the ideal expanding diameter for a perfect press fit of the bullet. The upper section of the expander incorporates a concentric ring that slightly enlarges the case mouth beyond the bullet diameter, improving bullet alignment. Additionally, the die's final taper can create a "bellmouth" on the case mouth when needed, which is especially beneficial when reloading lead bullets, ensuring consistent bullet seating and performance. This die set is designed for reloaders seeking exceptional accuracy and ease in their reloading process.
