So I need some help. As most of you know I load 9 mm on a DSD B. The problem that I am having is the every 10th round or so the case bells way more that I have it set. The oal is then a lot shooter on that
Round. Your thoughts please

Im wondering if mabe something has gotten lodged in the belling die somehow and it js giving you inconsitent bells. Possibly take it apart and clean it and see what happens.

Hey Dean,

Try not mixing those 38 super cases in with the 9mm cases.
