The RCBS Cowboy Shotshell die set is designed for 12 Gauge brass shotshell reloading, catering to Cowboy Action Shooters who desire period-correct ammunition.
This die set can be used with any RCBS single stage press that has a removable die bushing, handling sizing, de-priming, re-priming, and crimping tasks.
It works in conjunction with a shotshell press for powder filling, wad and spacer seating, and shot charging, finishing with a roll crimp for a complete handloaded brass shotshell.
