The bottle of Butch's Bore Shine that I bought last week seems to be working good so far.
Maybe they changed the formula b/cthe butch bore I have only took out traces of copper, after it passed clean I pulled copper with sweets.Iuse a dedicated copperremover after I have pushed my solvent of choice, its the only way I have foundfor a complete bore cleaning thus far.
