24 hours in Hoppe's 9, about 20 brush strokes, and the lands are beginning to emerge. The rinse water from cleaning brushes contains extremely fine black material. This black material results from soaking in either Hoppe's or Lead Cleaner.
In my opinion the barrel has no bulge because you can feel the restricting crud when passing either a brush or patch through that area of the barrel. Plus my sensitive little finger tips feel no external bulge. I am leaning to the idea that the rifle was stored barrel down and somehow a portion of the barrel was fouled.
Thanks for all the replies and help.
