If I were a betting man I would say you have bad primers or bad powder if you actually dumped out powder from the chamber. Try a different brand of primers with the same powder and see what happens. If you get the same results it's your powder, if not it's your primers. It's either one or the other.

On the other hand how much powder did you actually dump out? You may not have filled the case in those two rounds.
