I use carb cleaner haha great for any carbon and any powder residue. I once thought I'd do a good thing for a new tikka win mag I had and gave it a scrub with the bore brush and hoppes bore cleaner after 20 rounds or so. Worse idea ever took another 20 rounds down the tube to get it back in line. So now just clean for carbon and powder residue with patches an that's it.
