I have always squared my conventional dies by placing a machined washer between the shell holder and die body applying a little bit of pressure to bottem of die and lowering the lock ring and locking it into place..
Apparently thismethod not recomended on carbide dies (WHICHI HAVE DONE []) or competition (which I have yet to do)
So how do you go about squaring these things or do you.

Well, you don't want to cam over on the carbide dies is the only thing. Sounds like you are doing it correctly to me. Just use a washer big enough so you don't cam over. I had one machined that is 1/2" thick. You really don't want to cam over on the conventional steel dies either. Just a little pressure with the ram raised.

i don't understand.....please explain what is " cam over " ?

Like its explained in almost all reloading manuals. When you setup you FL die, you screw it down until it touches the ram when raised up. YOu then screw it down another 1/4 turn. So when you raise the ram, you feel it hit the die and then cam over.

You don't want to do that with carbide. It can shatter or crack.

aye. i understand.....i just was'nt sure what was meant by "cam over". ty for the explanation.[8D]
