I recently took a fall with one of my rifles, and the muzzle just outside the crown got a good ding in it. it is quite severe and i'm worried about it affecting the bore diameter or causing the bore to be miss-shaped at the crown, although to the eye it does not appear miss-shaped. The rifle is already at minimum legal length. do i need a new barrel? or can something like this be repaired? I don't want to fire it untill i can assure it is safe.
