Shellholder not included. Use of Hornady Match Grade Neck and Full Length Dies and Bushings: Hornady Match Grade dies have a separate, interchangeable neck size bushing (not included with die). The dimension of the bushing (inside diameter, listed) determines the neck size when the brass is inserted into the die. Standard dies size to SAAMI minimum specification and this is often not necessary, as a particular rifle, brass type and chamber may not need minimum dimensions. Less sizing results in less working of the brass. Using some loaded or dummy cartridges that fit the rifle’s chamber without excessive play, measure the diameter of the case neck. Subtract .001″ from that diameter and the result should be a reasonable starting point for the correct bushing dimension. Select a size that is at that dimension or just under it. Bushings work in both the neck and full length Match Grade dies. The bushings are available in .002″ increments.
