I had that same issue. So I sanded down that little plastic peg in the middle of the cover. Sand it down until it gently slips in the hole in the tray. No more flipped primers. I have no need for an extremely tight fitting lid.While we're talkin primer tools . I have the RCBS universal tool. Can some one tell me how to get the primers loaded.? Everytime I snap the lid down several flip back over.. No I can't close it gently.. It just doesn't happen.
