Could i have lead poisoning if i like to shoot at the shooting range?

Unlikely: I think it's unlikely unless you are holding lead bullets or shot in your mouth or are eating meat with lead shot still present.

Unlikely: Before OSHA rules went into effect,the most common group with adult lead poisoning were workers in battery recycling centers where lead was smelted and it entered the air/contaminated their gear. Exposure at an indoor range would be more than if outside. You could have a simple blood test done if concerned.
