We had problems with a range in Cardiff with some users
showing evidence of elavated lead levels. Best advice
was to reduce exposure to all forms of lead contamination :-
When shooting ensure any indoor range is well ventilated
with forced air extraction pulling smike and residues
down range.
If necessary wear a surgical style mask to filter out
residues.
Ensure you wash your hands and face after shooting
especially before you eat, drink or smoke cigarettes.
If you shoot, reload or handle large quantities of lead
bullets wear suitable gloves.
If you cast bullets ensure the area you cast in is well
ventilated and if necessary wear a surgical mask and
gloves.
Other forms of lead contamination should also be minimised.
Steve is correct in that most of the comtamination on
firing a standard cartridge is from the lead styphenate
(have I spelled that right?) in the priming compound. A
small qualtity is also vapourised as the unprotected
lead bullet passes down the barrel but its small in
comparison to the primer. The CCI ammunition also
uses a lead free primer I believe.
Most people also don't realise that lead can be absorbed
through the skin so handling large quatities of lead also
has its risks.
Hope this is helpful.
Regards
Jerry

I think on the NRA website (US NRA) there is something
about range construction. They produce a book on the
subject.
