I just scored on a Savage 110 in 270 Win today. Picked it up for $250. The bore looked really good but the rest of the rifle has been beaten and abused. The stock has very noticeable surface damage which I am thinking about replacing with another wood stock unless the fix is easy. The barrel on the outside has rust. How can i fix the rust and potentially the bluing? Would copper wool be a good start on the rust? I bought this to bring it a second life and make it look nice.
