So I have cast lead for years and this is a new problem I have never had. I am using a NOE 175gr high tec flat nose bullet and loading to 1785fps the bullets shoot amazing groups when everything comes together but I keep getting a lead ring at the throat of my bore causing the round to stick or jam any clue on the cause of this would be helpful I have just started casting for my AR platforms so this could be a common problem with them and I wouldn't know
