The RCBS Cowboy Shotshell die is designed for reloading all brass shotshell ammunition, fitting in any RCBS single stage press with a removable die bushing.
It sizes, de-primes, re-primes, and crimp brass cases, with the press handling powder, wad seating, and shot charges.
The die allows for a complete handloading process, including the final step of roll crimping the case mouth with an over shot card.
