Lead has to enter the body to be harmful. The ability to absorb lead lead through touch is not existent for all practicable purposes. For that matter one could swallow a bullet and it would pass without being absorbed. Lead oxides that are breathed are more of an issue along with and lead sulfates/sulfides.

The primer used today provide more potential exposure to lead compounds than the bullet.

If you are really concerned you should have you physician do a base line lead blood level test (it is not really lead but lead compounds) and get checked to an annual bases to see if your levels have changed.

Shooting indoors with little ventilation poses the biggest risk - breathing the primer residue - Lead styphnate.

Ask yourself how often do you hear of some get /having lead poisoning from reloading or even shooting.
