Its a problem. A very nice tool with an ingenious design, but they made that blinkety, blanking ring .002 too small so it sizes the boolits down when you crimp. I have a diamond stone and a lathe, but I'm afraid to proceed because I have never polished a piece of carbide before (at least not to a high shine), and I believe it needs a fairly bright finish.
All I know it that I had 800 45acps that where bulged from stabbing in unsized boolits and the Lee factory crimp die has made them feed flawlessly in my 1911's. Of course the problem is, that the carbide ring sized the boolit in the case down to .450 which of course leads the living **** out of my barrel.
I love the design, but that ring has got to open up some.
Any ideas?
