Alright. Been breaking in my new barrel. Using hornady brass as thats all i had. I received some adg brass and fl resized checked it and it wont chamber... I've ran my gauges over evrything and it is all the same as a hornady piece.
Any suggestions?
 
give it a shot. a small base die will cover the base body, the shoulder, etc so you will atleast start at the bare minimum tolerances for the round.
 
Clean and dry? I was with my son he was running rounds on his dillon.
All of a sudden rounds would not plunk check.
His catch container was dirty, just enough to foul the rounds.

Is your guns chamber dirty?
