I think you have read a biased journal on that point.
It was other substances that affected ammunition workers . Phosphorus poisoning was one.
Besides, as you say, it's the same lead used world wide today in munition producers and err, nobody gets ill affecting production.
I know people that have worked at Radway Green for decades, guess what, they aren't ill or affected production.
You are confusing lead derivatives and compounds with the low reactivity of static lead as a metal. Unless you are sucking a lead lollie your good
Every day thousands of medical professionals handle lead too.
And I drink water from a lead pipe and all my neighbours do too. One dear old lady passed away at 96 after living here for 50years.
Now, I don't doubt your findings one bit but I would definitely question as to whether banning lead shot is going to transform the health of the nation.
Us shooters are in a minority so all the victims of lead must be getting it from somewhere else, not from us!
Maybe it's all the zinc coated products that surround us or maybe it's been sprinkled on us from above, I don't know nor care because frankly in this life there are only two eventualities, taxation and death....
