RCBS Case Forming Dies *Gruppo

Most RCBS Dies are manufactured with the standard 7/8”- 14 thread and are designed for use with a shell holder having a lip thickness of 0.125”. The primary exceptions are the .45 Auto Rimmed, 11 mm (.43) Mauser and .43 Spanish. These must have a shell holder lip thickness of 0.150”. Any variations of these dimensions may cause headspace or insufficient sizing problems.

RCBS Dies are furnished with a steel lock ring with a “hex” design that allows tight control over precise alignment. A solid brass setscrew 
locks the ring securely, yet will not damage the die threads. Once the large lock ring on the die is set it can be locked in the desired position by lightly tightening the setscrew. The die will then hold the proper setting and may be reused without readjustment.
