    Another site thought it looked like it was heavily leaded and suggested JB bore paste , so today I put a bunch of patches through it, and got a lot of grayish black out of it.
    Going to put more through until comes out clean.

    If that doesn’t work, maybe try one of the many chemicals for removing copper. I would think that your schmutz is from jacketed and not lead bullets.
