I use cake pans a lot for reloading stuff and a few other pans you can lay a lot of cases on and then just roll them a little by tilting it different ways.
I watch for defects every time I pick up a case but once they are empty, de primed, flared or expanded, trimmed - I pick out a lot of bad ones during trimming, I'll dump a pile in the cake pan and just watch them roll back and forth. Any kind of "clinker" just sticks out like a sore thumb. I do this last thing before "putting any money" in them. Last check, then prime and powder they are ready.
