I realize that is what they all claim. But if it is really about the potential lead exposure, why will they sell bare lead 22lr and let people shoot hundreds of rounds of it?

Which really puts more lead in the air? A couple of hundred soft swaged lead 22s (hot enough to run 1200 fps or more) or 100 of my mild hard cast 44 mag reloads (at 900 or 1000 fps)?

Seems to me that it would be the 22s - especially since people shoot so many of them. But since the range sells them, I guess that makes it OK?
