I have noticed a few that didn't fit properly before, usually its a gouge or a burr caused by extractor, but I've seen a couple that appeared to have a thick rim.
I have found a few (45's and 223's) that didn't want to fit under the shellholder of my Progressive press, after a quick inspection without finding an obvious burr or easy fix, I chalk it up as a out of spec case and just chuck them in the scrap bucket.
