Lyman's newly improved sizing dies now feature precision-drilled 90-degree hole spacing, significantly enhancing lubricant flow efficiency-even when using today's harder, high-viscosity bullet lubricants. This critical upgrade ensures consistent lubrication application throughout the sizing process, reducing friction and promoting uniform bullet surface finish. Engineered for superior performance, each die incorporates a carefully tapered mouth to simplify bullet insertion and ensure concentric entry. The hardened interior surface of the die promotes precise alignment during bullet passage, preserving an optimal cylindrical profile that enhances both accuracy and performance in loading. These dies are dimensioned to match industry-recommended bullet diameters for a broad spectrum of popular rifle and handgun calibers, ensuring compatibility and precision across various reloading applications. Complementing the dies, Lyman's top punches are CNC-machined to perfectly match the bullet nose contour, eliminating the risk of deformation during the sizing and lubrication process. This precise nose-to-punch fit ensures bullet integrity is maintained, making these tools indispensable for reloaders demanding peak performance and consistency from their handloads.
