MD, It looks like you're just going to have to trilobite the bullet and scrub it out.
Have you tried a Lewis/Hoppe's lead remover yet? I'm not sure if they make one for a 30 cal. But, with your machine shop you could whittle one down with a lathe.
On the Foul Out - it is working if you get approx. 1/4 volt with no load. It may go lower when set up in the bbl with solution, I didn't check that voltage.
It is very important that you have an oil/cleaning solution free barrel before you use the FO or you will get a false "clean" indication and it does nothing. Be sure to scrub the bbl out thoroughly with Outer's Crud Cutter or a similar degreaser.
