This neck sizing die with interchangeable bushings brings an advanced level of technology and precision to shooters in all disciplines. Similar in concept to the Redding Competition Seating die, the cartridge case is completely supported and aligned with the sizing bushings before sizing begins. As the sizing starts, the case remains supported in the tightly chambered sliding sleeve while the floating sizing bushing centers on the case neck. The micrometer adjustment of the bushing position provides precise conrol to the desired amount of neck sizing length. Dies supplied without bushings. Dies sold separately or as part of a set.
