I am just itching to get home tonight and load more RMR 124gr RN, but I ran into an issue the other night. I am using mixed brass, LCT, and a Lee auto drum. I notice on say 1 out of 10 bullets there is a slight bulge on the round and I can feel the FCD iron out the bulge. At first I thought maybe I wasn't flaring enough but the bullets sit in the case for the most part without falling out. I plunk tested all of them but 2 felt a hair too tight so they were broken down and re done. I did notice that if I hold the bullet until my fingers meet the die and there is no bulge.
Any ideas on this one?
