Reloading with precision, smoothness, and versatility is made easy with Lyman precision dies, designed to handle high-volume reloading with ease. Each die is vented, polished, and heat-treated to guarantee toughness, then polished with a micro-finish to ensure smooth operation throughout the reloading process. Lyman's pistol die sets are equipped with solid tungsten carbide sizing rings, delivering the durability and precision reloaders expect. The one-piece decapping rod, made from hardened, heat-treated tool steel, is built to handle tough depriming tasks, even with crimped primer pockets. As the original innovator of the tungsten carbide sizing die and the multi concept, Lyman adds extra seating screws and introduces the two-step neck-expanding die for maximum versatility. The multi-deluxe die sets offer all-steel construction, ensuring top-notch reliability and consistency for reloaders. Lyman dies are compatible with all widely-used presses that utilize the industry standard 7/8-14 threads, including those from RCBS
