Engineered for optimal performance in modern reloading setups, Lyman's refined sizing dies now include 90-degree hole placement to facilitate complete lubricant flow-even when using firm, cold-weather bullet lubes. The dies' beveled mouth leads bullets seamlessly into a hardened, precisely dimensioned interior designed to maintain exact cylindrical form. Internal specs are tailored to recommended dimensions for a wide range of popular handgun and rifle cartridges. Designed to work in unison, Lyman's top punches are each machined to perfectly match the nose shape of their corresponding bullet, eliminating nose flattening and preserving bullet profile throughout the reloading cycle.
