With a focus on modern bullet lubrication challenges, Lyman has refined their sizing dies to incorporate strategically placed 90-degree lube holes, greatly enhancing performance with dense, high-viscosity lubricants. These dies feature a tapered entryway to facilitate consistent bullet entry and a fully hardened inner surface that maintains bullet symmetry and dimensional accuracy. Caliber-specific internal tolerances are designed in accordance with standardized bullet diameters, ensuring reliable compatibility with mainstream rifle and pistol cartridges. Lyman's top punches complement this precision with bullet-nose-specific machining, eliminating deformation and supporting flawless bullet seating.
