Multiple marks in barrel - Shaw 10/22 .920 Profile Bull Barrel 18 in Straight Flute Threaded

After cleaning, I ran a bore scope down the barrel and found multiple marks or scratches in the last 2 inches of the bore. I gave this barrel three stars because I had a barrel like this before, and it was extremely accurate but didn't have a bore scope then and don't have access to the old barrel. I'm not sure what could have caused this, but it's a little concerning. Not sure if I will try shooting it or not.
