Lyman's newly improved bullet sizing dies now feature 90-degree hole spacing, a significant advancement that allows even today's toughest hard lubricants to flow effortlessly through the die body, ensuring consistent and thorough lubrication across a wide range of bullet alloys. Each sizing die is equipped with a precision-engineered tapered mouth that guides the bullet smoothly into a hardened interior channel, aligning it perfectly to maintain its true cylindrical form during the sizing process. These internal dimensions are meticulously calibrated to match the recommended diameters for virtually all popular rifle and pistol calibers, guaranteeing accuracy, reliability and uniformity with every bullet passed through. To further enhance bullet quality, Lyman's top punches are CNC-machined with exceptional precision to match the specific nose profile of each bullet, eliminating any potential for distortion or deformation during sizing.
