It is the LEE #10 shell holder that I just got. I am pretty sure it is the diameter of the rim causing the problem. My measurements of the brass's extractor groove don't show any differences.
I must admit that I was surprised to be blaming Norma brass as the culprit I was always brought up being told it is the best. (Sorry Norma)
It has me even more surprised that the long standing LEE company could be selling stuff this far out of whack. (Wake Up LEE)
If I have any luck I will let you all know.
