Designed with precision and reloader efficiency in mind, Lyman's enhanced sizing dies feature a 90-degree hole configuration to optimize the flow of lubricant-even when using ultra-firm modern bullet lubes. The tapered die mouth centers bullets effortlessly, feeding them into a heat-treated and hardened steel bore that guarantees a uniform cylindrical profile. Internal measurements are precisely tailored to industry-recommended sizing diameters across a wide selection of popular handgun and rifle calibers. Each die works seamlessly with Lyman's top punches, which are custom-machined to mirror the exact nose shape of your bullet, maintaining aerodynamic form and preventing any nose deformation under pressure.
