Without neck tension uniformity, respectfully, your observed data is suspect! For the record, I made that mistake for years!Older thread I know. I saw this as I was browsing.
Probably a dumb question that I already know the answer to, but is there a chance that throwing a crimp on the rims would help with cases that have not been neck sized prior to loading? I'm thinking maybe by using a Lee FC die on them for a light crimp?
I did a little googling a while ago on this subject. The opinions I saw make it sound pointless. Thought I'd see what you folks think anyway.
