Short Action Customs Modular 6mm GT Bushing Neck Sizing Die

The Short Action Customs Modular Neck Sizer Die has a unique design where the cartridge's body geometry is sized by the die body, the cartridge's shoulder and neck geometry are sized by a "Neck/Shoulder Bushing" (sold separately). This allows one die body to be used for the whole cartridge family. Furthermore, the Modular Sizing Dies are precision machined with the main focus of properly sizing your fired brass. The modular resizing dies will size the base of the cartridge slightly more than the shoulder. This die is considered a full length sizing die. After studying precision CNC machines and tooling, SAC designed the Modular Sizing Dies to utilize a series of shallow tapers, not threads to properly center and secure the Solid Decapping Pin. The tapered geometry offers unparalleled concentricity and repeatability. Last but not least, they designed the cartridge sizing geometry to size a little more at the base and a little less at the shoulder when compared...
