What if one flipped over and became accidentally seated anvil side down??
Toss the unprimed case out (oil can it), don't fool around with it. It is not worth the risk, IMHO, especially one that is loaded reversed. Your depriming rod will be working exactly the same way as a firing pin. In my way of thinking, a primer is nothing but a miniature hand-grenade, a very sensitive one, something to be very careful when handling.
P.S. - The medical profession doesn't have eyeball transplants perfected yet!
Always wear safety glasses when working around primers or with any other reloading activity.
