Hey guys, I'm having sporadic head space readings on my Wilson Case gauge using Lee full length 223 dies. I'm re-sizing range brass and for the life of me can't get a consistent shoulder bump. Out of 20 cases resized, 5 are flush with the lower step and 4-5 are flush with the upper step. What gives? I'm having to bump some of the cases .006-.008 just to get them to fall below the upper step. Also I'm having trouble bottoming out the shell holder with the die using monarch brass (nny stamped).
