This two-die set from RCBS is engineered for full-length reloading of bottleneck cases chambered for the 8mmx58R Danish Krag cartridge. The set includes a Full-Length Sizer Die equipped with an Expander-Decapping Unit and a Seater Die fitted with a Bullet Seater Plug and built-in roll crimper. The full-length sizer brings cases to SAAMI minimum cartridge dimensions while vents and controlled headspace reduce the risk of case damage during sizing. The dies ship in RCBS’s characteristic green die box for storage and transport.
