This neck sizing die with interchangeable bushings is similiar in concepts to the Redding Competition Seating die. The cartridge case is completely supported and aligned within the die before sizing begins. As the sizing begins, the case remains supported in the chambered sliding sleeve while the floating sizing bushing centers on the case neck. A micrometer integral to the die body allows the user to precisely control the amount/ length of the neck that will be sized. Dies supplied without bushings. Dies sold separately or as part of a set.
