Whenever, I full length size used brass it will not chamber in my 240 Weatherby Encore. If I use my new or my fired brass it chambers. It is driving me nuts trying to figure out what it wrong. Case length is ok. Just purchased 100 once fired empty cases and cannot make them work. There appears to be a miniscule ring ahead of the belt which is keeping my ammo from chambering. Any advice willl be appreciated.
