Was out shooting my S&W 29 with some 300gr TC midrange lead reloads I cooked up. I think they were a bit soft. Probably doing about 950 fps. Anyway, I got some leading. Got 99% out of the barrel with the hydrogen peroxide/white vinegar solution. The cylinder mouths took some elbow grease. Got most of it but some remained. Anyone got any new or unique methods for lead removal?
