The rangemaster for my dept. (a guy who literally plays on the range, polices brass, sets up and takes down targets, does the landscaping, etc... all day long and is on the firing line whenever any shot is fired) has never had any problems with lead exposure, they make him get tested every 6 months to be sure. Sipping on a diet-coke while reloading isn't going to make you sick. Well the diet coke might, but lead won't.
Civilize the mind, and make savage the body.
