Re: Copper and Lead Fouling?
There is absolutely no reason you would want copper in your barrel. Sweets works well, the ammonia reacts with copper and turns the patch blue, when the patch is no longer blue you have all the copper out. Be warned, it's going to take a long time with a factory barrel. I like KG12 better, it's acid based and doesn't turn blue, unless you have a bore scope it's hard to tell if you got all the copper out, you can tell somewhat by looking in the muzzle end of the barrel, you can usually see copper fouling there with the naked eye and a light. The KG12 works much faster than sweets
