RCBS’ 38 S&W 3-Die Cowboy Dies are built to slightly different dimensions than their regular dies to allow optimum sizing, expanding and crimping needed to load great lead bullet ammo. The 3-Die Carbide Roll Crimp Set is intended for loading straight-wall cartridges for period firearms used in Cowboy Action Shooting. The design allows optimum sizing, expanding, seating and crimping for lead bullet ammunition. Mfg: Rcbs
