Hornady dies represent the finest in machined craftsmanship, and their Neck Sizing Dies are no exception. These dies can help eliminate some of the issues often encountered with full-length cases, such as excessive headspace or oversizing, and help your handloads re-align with the chamber, resulting in better accuracy and longer case life. They feature a Zip Spindle design, high-grade internal finish, Sure-Loc ring system, compression washer, retainer ring and a titanium-coated sizing ring. Plus, their Elliptical Expander provides extremely smooth neck sizing and reduces friction and case neck stretch. Neck Sizing Dies should only be used on cases that will be fired in bolt-action or single shot rifles.
