It may have been on the ram when you deprimed the cases and was reseated into a case when you started priming. What I meant about "righting" themselves is when you orientate them - anvil-side up - to load them into the tube or priming tool so they are ready to insert into the case. As the weight of the priming compound is what orientates them, the spent primer will not position itself like the others. It's just that old adage - "[color=#FF0000]█[/color][color=#FF0000]█[/color][color=#FF0000]█[/color][color=#FF0000]█[/color][color=#FF0000]█[/color] Happens"!
