Redding 7MM TCU Competition Bushing Neck Sizing Die

The Redding Competition Bushing Neck Sizer Die is similar in concept to the Competition Seating Die, the cartridge case is completely supported and aligned with the sizing bushing before the sizing process begins. As the sizing process starts, the cartridge case remains supported in the tightly chambered, sliding sleeve as it moves upward. The resizing bushing self-centers on the case neck. The decapping rod is maintained in precise alignment by using the internal parts of the die as a linear support much like that of a firing pin. Meanwhile, the micrometer adjustment of the bushing position delivers precise control to the desired amount of neck length to be sized. Bushings and shellholders sold separately.
