RCBS two-piece mold set for rifle cases. The set consists of a full-length calibration die (with expander/decapping part) and a ball-setting die. The Full-Length Sizer Die calibrates the sleeve back to factory dimensions. The Headspace is held to minimum tolerances during calibration to avoid altering the full length dimensions of the sleeve. The calibration die has a vent to prevent damage to the sleeve caused by trapped air and/or excessive lubricant. The ball setting die has a built-in Roll crimp for securely holding the ball tip. RCBS mold sets are supplied without sleeve holder.
