Most of my guns clean up with a few patches with Marvel Mystery Oil, after shooting cast. My measure of clean is when a clean tight patch comes out of the bore as clean as it went in. Sometimes I get lead, comes out with a Lead Away patch, by Kleen Bore. Every now and then I get a grey tight patch after cleaning for a while. This means lead. I use Kroil on a tight patch, tight enough so the patch squeaks as it goes through the bore. This patch will take out some tiny pieces of lead. It doesn't take much lead to get a tight patch grey. I do this until tight patches come out clean.
Other than an electric machine, does anybody know of a better way to get a little lead out of the bore?
Thanks;
