Redesigned for maximum efficiency, Lyman's improved sizing dies feature 90-degree lubricant hole spacing, allowing for uniform lubricant application even with today's increasingly hard bullet lubes. Each die includes a flared entry to gently align the bullet into a hardened steel interior that supports concentric sizing and a true cylindrical finish. The interior geometry is precisely matched to recommended caliber dimensions for both rifle and handgun rounds. Accompanying top punches are machined with bullet-specific nose profiles, eliminating the risk of distortion and ensuring that even the most detailed bullet shapes retain their form during sizing.
