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.
2nd cleaning with Keoil and JB bore paste.
Left is towards front of barrel about 6" from end.
Right is from after 1st cleaning
