Lyman's improved sizing dies simplify even the most demanding reloading tasks with their 90-degree lubricant hole configuration, which allows for smooth and even distribution of today's harder, high-viscosity lubes. These dies include a tapered lead-in for efficient bullet entry and a hardened interior core that maintains concentricity and provides a true cylindrical finish. The internal die dimensions align with recommended tolerances for all popular pistol and rifle calibers, ensuring ideal fit and performance. To preserve bullet form during sizing, Lyman top punches are CNC-machined to precisely fit each bullet's nose, eliminating any risk of distortion or damage.
