Well, this just happened to me for the first time. Just got done eating some leftover taco meat (grind) from my cow elk this November. Picked 3 fragments of lead out of mouth while eating taco salad. Thank god it was me and not my wife or 16 month old that also ate on the same package.
Cow elk ever so slightly quartering-to shot. Double lung where the to-me shoulder meat took some damage, but no scapular damage at all.. thought we did a good job trimming. We lost some shoulder meat and a good bit of rib me on the exit side.

I work in radiology and am considering bringing the grind in and running it through a CT scan just for fun.
