If I'm going to make these adapters for universal use, then it looks like I will need to put a counterbore in the part like you said.
Just out of curiosity, If you happen to have a RCBS die laying around, would you please measure the rim for me & let me know what diameter it is? I'd like to find out if that is a standard RCBS diameter, or if the third hand die that I have is just a weird one.
Thanks,
