At that time, I was using a loading philosophy of using a load density that would prevent a bullet from being pushed back into the case far enough to chamber the round on top of a bullet stuck in the throat. So, that philosophy saved the day. The incident led to a whole rethink of loading and shooting practices. I've never had an unpowdered case again.
Another practice I used was for reduced powder charges. The charge would always be more than half the case volume so a double charge would overflow, or a double charge would still be within the usable range for that powder. Now I also shine a light into every sing case before seating a bullet/boolit. No exceptions. So far so good.
