Lacking empirical evidence, I have to call that one.
Moly is just another nasty that years down the road doctors and old folks will say we should have known better to handle and breathe the powder and the residue in the air when shooting it and it can then be like asbestos is now.
Ok, for one thing, we're not snorting the stuff, Paul. Far from it.
And by the time we die of moly ingestion, the lead poisoning from shooting all those rounds will have driven us totally and irreversably mad.
Everything can be dangerous if not used properly. Hell, there are Material Data Safety Sheets on good old H2O, for Chrissakes!
Feed enough diet cola to rats in a test environment, they die of cancer.
An Air Force recruit died of acute water poisoning during confidence training.
"Put yo brain in a turtle's haid, he peck out his a**" is a famous saying.
Life today is a matter of risk management. McDonald's will kill you. Mom always told me I'd go blind from doing a certain something. Flying is inherently dangerous.
