Alright guys hope yall can help me with this problem. When I resize my brass with edge dies I was told to do it without the expander ball in it except when sizing up from 300 ultra. When I do this what would cause the neck tension to be fine on some and tight on others. I would say 1 out of every 5 will be quite a bit tighter than the rest.
I have not used the Forester reamer, so I can't help you on that. I have been using the Sinclair neck turning tools. I think you will find when you are done that it will help your uneven neck tension when seating your bullets.
