I recently did a complete take down of my m91/30 mosin to install a timney trigger. When I got it out of the stock I noticed a small rusty spot on the barrel and when I cleaned away a little bit of the rust there seemed to be some pitting in the area, which I took pictures of, then sprayed it with CLP. It doesn't seem too major, but it does have me a little worried, is it still safe to shoot as long as I keep it oiled so it doesn't corrode further?
