Powder fouling and lube residue that has varnished, from the sounds of it. If it really needs to come out, try a solvent like Hoppe's. And it is a good idea to not scratch at the bore with anything metallic, rifling is only about .002" deep on a 22 rimfire and old rimfire barrel steel is very soft.
