I've got an older blued 110 in .270 that I'm considering using as the base for a .260 build. The stainless bolt on this rifle is rather dull, and would need to be shined up a bit to better match a stainless barrel from Shilen or McGowen.

Any recommendations on what technique or compounds might work best? A search showed me some folks have used a polishing wheel on a bench grinder, but I don't have one.
