I took a barrel off of a new Savage 111 in 270 to make a 6mm AI out of it. I put the new 270 barrel and barrel nut on an older 110 action in 270. I put the original recoil lug on it since it was bedded for that lug. I put a new 270 case in the action as I screwed the action on until it snugged into the barrel. I have 2 or 3 threads showing on the muzzle side of the barrel nut after tightening the barrel nut. I do not ever remember seeing that before. Did I do something wrong? Any ideas? ???
