I would not be surprised either. Especially on skeet/trap fields and on sporting clays ranges were you are shooting TONS of lead shot, lots of times near water.

I don't think we need to be shooting solid copper at crows & vermin (with high powered rifles) were the bullet would go on forever. That's why (at least one reason) we have frangible bullets right. Is there another element soft as lead?

Why would they ban lead rifle bullets? Shot I can see... but how are ducks gonna find the .300RUM 180gr slug pushed 11" into the earth????

Not doubting anyone; just doesn't make sense to me. I'd like to see some literature on it.
