NOTE: This is for a Die-Only. These dies do not come with a shellholder. They are compatible with common shellholders from Redding, Hornady, RCBS, etc. They are also compatible with our ZERO Modular Shellholder System Following the resounding success of our M-Series Sizing Die, the mission became to take as many of those industry-leading features as possible and push them into a traditional 7/8″ die, keeping the price point under $300. We think we nailed it. Introducing the ZERO S-Series Sizing Die KEY FEATURES Precision Ground Expander Mandrels (all dies ship with a .002 neck tension mandrel, or add more increments with our MANDREL KIT) Full-Length Neck to Extractor Sizing Spring Ejection for Spent Primers Replaceable Steel Decap Pins Reamer Cut to Exacting Dimensions for a TRUE Size (no more sticky bolt after the second firing) Hydraulic Shoulder Pressure Relief 100% Made in AMERICA All dies ship with an Area 419 ZERO Universal Die Ring, a spare decapping pin and necessary install/removal tools. After testing them all, and finding everything we like and didn’t like, and working with thousands of customers and a variety of industry partners, we believe this is what a 7/8″ sizing die should be. We think you’ll agree.
