I have a Remington 7mm-08 that has similar marks in the barrel. I discovered them after years of use after a full cleaning out of the copper when I also got access to a bore scope. After 5 fouling shots it was right back to half MOA shooter. I have not worried about it since. Tooling marks like those are more common than most of us would think in factory barrels.
