Guys,
I don't think the problem with ringers is a problem with the brass getting wet. If this was the case 50% of the brass that I pick up at are range would be useless. I literally pour water out of the cases that I pick up during the early spring and late fall.
Does anyone think that the problem could be primer anvils or the punches on the sizing dies. The few cases that I have come about that did contain some ringers did come from a match that we had that day. All that brass was picked up that day and nothing was wet.
