Lyman's improved sizing dies now feature 90-degree hole spacing, significantly enhancing lubricant flow-even when using today's harder, more viscous bullet lubricants-making the lubrication process smoother and more effective. Engineered with a precision-tapered mouth, each die ensures seamless bullet entry and exact alignment, while the hardened steel interior maintains the die's dimensional stability over extended use. Designed with precision in mind, the internal diameters are matched to industry-recommended specifications for nearly all standard rifle and pistol calibers. Paired with Lyman's precisely machined top punches-each contoured to match the bullet's nose profile exactly-this system eliminates nose deformation, guaranteeing consistent, high-quality results with every round.
