Wish I could, but I live in the UK and they wont deal with us english guys direct. And trying to get parts is impossible. Might have to be a new micrometer die. [img]/ubbthreads/images/graemlins/confused.gif[/img]
Talked to the rcbs lady this morning... she said the part # you gave me was for a 20 caliber seater. She also asked if it was a "clicking" as in with a detent model, or the o ring model.
Let me know and ill try again.
