This may have already been covered, but I couldn't find it. Have been having a lot of bulged brass picked up from matches that are so bulged it makes a ridge at the base of the case after resizing. Thought at first maybe it was 9 major, now I'm thinking it is Pcc as they outnumber open 9's at our range. Just wondering if I am right or wrong. Appreciate any thoughts, not that I can do much except screen the brass better. Thanks
