Could be a formula for creating a superfund site. If you do decide to
do this you should visit a facility which salvages batteries first. It
will change your mind.

It probably wouldn't make any difference for black powder ammo but
that lead probably wasn't as pure as you thought. Battery posts and
grids usually are made with antimonial lead which contains 7 to 12%
antimony along with some copper, tin, and arsenic.
