Head scratcher.

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?

I would run it through a small base die. that will take it down enough to chamber hopefully.

Thays what im guessing is the base is just so slightly big.

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.

would the adg brass chamber before sizing?

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?
