Hangfeyr- The only dumb question is the one that is not asked. Stuck in and around the tongue in cheek above is some sage discussion. My $.02 worth would start with the observation that standard big game cleaning/butchering practice includes cutting out the wound channel and all blodshot meat around it. If you leave the bullet in your carcass you are not properly doing the job. More to the concern of your question, a few years ago, when at the ER for other reasons, I was having some blood tested. I asked the doc to also test me for lead in my blood. The doc asked why and I explained I was in my 5th decade of life and had been a hunter and shooter since age 6. I had consumed harvested game, including beaucoup ducks and geese from the lead shot era, my entire life. I target shoot 10 or 12 times a year. In addition, I have melted lead three or four times a year to cast bullets, fishing sinkers and decoy wieghts. And perhaps the worst, I am an avid freshwater fisherman with the terrible 40 year old habit of biting lead splitshot closed. The blood test came back negative, no trace of any lead.
