I was wondering about the lead issue in using the tumbler also. I have heard this (here on the forum) and wonder really how much lead is actually in the media after polishing the cases? Since I never run bullets or cases with bullets in them in the tumbler, where is all this lead coming from, from inside the case, I don't think so since I only use jacketed bullets and all my lead goes out the barrel. I would guess it is more carbon from burnt powder rather than lead, but is there any proof that there is lead in the media????
