It looks like there are some pits that may have caused by moisture and rust,but they seem to fill in with copper as it's shot.I have a 25-06 barrel that's way worse than yours,but it still shoots great.I think moisture can get into the carbon fouling in the barrel and cause those little rust pits.Anything I have that's not stainless gets a lightly oiled patch through the bore at the end of a shooting session.Also,I've had a couple scopes go bad on me and cause something similar to happen.No real bad change in group size,just a noticeable one.
