Redding Competition Bushing Neck 3-Die Set, .308 Winchester

The Redding Competition Bushing Neck 3-Die Set for .308 Winchester (Redding part no. 58155) gives precision handloaders full control over neck sizing in a three-die set built for the competition bench. Redding designed the set so the case is fully supported and aligned in a tightly chambered sliding sleeve before sizing even begins, with the resizing bushing self-centering on the neck for tighter concentricity than a standard die. A firing-pin-style support keeps the decapping rod in precise alignment through the stroke, while a micrometer adjustment lets you control exactly how much of the case neck gets sized. The set includes a Competition Bushing Neck Sizing Die, a Body Die, and a Competition Seating Die, and is built for shooters who prep their own cases and prefer to skip a sizing button altogether.
