I am cleaning my 30-06 that is older than I am. It shoots great. Every time I clean it I am getting black stringy looking stuff coming out on the patches. Any idea what it is? It seems like I am never going to get this barrel clean. I know the blue is copper fouling. I did buy this Sako L61R used and I had my gunsmith look it over with a clean bill of health. I am wondering if it was never cleaned and I am just removing decades of carbon and fouling. I use a carbon fiber Tipton rod and bore guide. Any response is appreciated as I have never seen this in decades of cleaning rifles.
