Hi all dies wanted RCBS is best can anyone help out.

The factory "off-the-shelf" .500 Jeffery dies are C.I.P. 2-15-00 Dated dimensions for the Jeffery. The .500 Schuler is different. If you don't know your chamber specs best bet would be send RCBS fired cases to be sure.

My gun smith has the action and barrel though the barrel is not yet fitted to the action at this stage, he did say that RCBS where the best dies to get,also he said was that it is a good idea the dies are a touch smaller then the guns chamber.
