One of my many Savage barrels is/was a brand new "take off" (10-fp-sr)
that I purchased on one of the forums. It has several real bad pitted areas that show up in the bore cam. These pitted areas also have button rifle tooling marks right through them. These areas are gradually "smoothing" out and the barrel is a decent shooter.
As long as yours shoots good then like the others say don't worry about it.
