I've been working on cleaning my T/C 30-30 bbl.I have noticed that there seems to be something on the lands of the rifling when I look down the bbl.I don't know if it's lead or possible pits.I'm guilty of not cleaning properly.I have cleaned the bbl with a good solvent and ran clean patches through the bbl first.Then I started using a nylon brush with a patch of Hoppe's rust and lead removing product down the bore.After a number of passes the patches are coming out black.I have run the patches several times through the bore and they are still coming out black.Is this an indication of excessive lead still in the bore or is something else happening.I have read the one will still get black patches when cleaning if using a bronze brush and good solvent so that why I'm using a nylon brush.I'm thinking that it MAYBE lead.The bullets I've been shooting were sized .309. I have not had the bbl slugged to find out the throat size yet.There are a couple I want to take to the gunsmith and have done.One is a Ruger M77,the T/C bbl,and a7.7mm Jap I would like to shoot
Thanks for the help
