I recently finished loading over 700 rounds last weekend. As many of you know, when you remove the primers in the first stage of a progressive reloading press there is an interesting little "poof" of smoke that appears. I have just come to find out that the majority of primers contain lead. I am not overly concerned with exposure to lead and I simply wash my hands after handling lead bullets. Even so, ingestion of lead is definitely not a good thing and I think inhaling it is probably one of the worst things one can do. So my question to everyone on the forum is: Do you think the vapor produced from removing primers contains lead? I think wearing a mask is a little extreme, but if the vapor does in fact contain lead, it probably isn't a bad idea. In addition, what does everyone do to avoid exposure to lead?
