The Redding Competition Bushing Neck Die Set for 300 Winchester Magnum includes a Competition Bushing Neck Sizing Die, Body Die, and Competition Seating Die. Built for competitive shooters who demand precision, the Type S Bushing Style Neck Sizing Die allows you to control case neck size and tension with interchangeable sizing bushings available in .001″ increments.
Both the Bushing Neck Sizing Die and Competition Seating Die incorporate micrometer adjustments for precision work. Neck concentricity improves through minimal sizing and the bushing’s self-centering action on the case neck. The adjustable decapping rod lets you position the bushing to resize only a portion of the neck length if needed, giving competitive reloaders exceptional control over ammunition specifications.
The Body Die performs full length resizing of the case body and bumps the shoulder for proper chambering without affecting the case neck. It is intended for use only to resize cases that have become increasingly difficult to chamber after repeated firing and neck sizing. The bullet guide to seating stem fit in the Competition Seating Die is engineered so precisely that the seating stem can actually be demonstrated to “float” on a column of air.
