I use KG 12 and a nylon brush. Gets rid of copper easily without the worry of ammonia based cleaners remaining in the barrel too long. Leave KG 12 in the barrel for about two minutes, scrub with nylon brush a few times(5 or 6 passes) run a few patched thru to clean out the gwadoo and instant shiny barrel....easy peasy. Follow with a bit of oil on a patch for ultra shine and protect against future rust.
That didn't work for me at all. Have you looked at it with a bore scope. I did. Perhaps it depends on the bore and amount of copper you are dealing with.
