One thing I've done to detect run-out-y brass is to have a level mirror or sheet of good clean glass, and roll the cases on the glass. It is amazing how some cases are heavy on one side, and will jerk across the glass and stop at the same spot every time. And yep, they have more runout, too.

Dave,
Great idea--and a lot cheaper than buying a tool that measures case-body thickness.
Have owned one of those tools for a while, and yes, it shows that case bodies thicker on one side than the other also tend to have more run-out. But most of us have a mirror!
Have recommended the mirror method for checking bullet runout for years, but....

All of my run-out seating issues went away once I started using precision dies. Redding is my bottom line choice now. Never less.

Even great dies won't make up for crap brass. I was reminded of this at the loading bench recently.

Never tried the mirror trick.
Will have to check that out.
Thanks,
