Anybody casting a keel and interested in a source for quite a lot of lead?
A Cincinnati area private target range has a few years worth of used bullets
for sale.
You come and get it, pay less than scrap price. I guesstimate several tons
(20+ 5 gallon buckets)
Bullet lead is probably about 98,1,1 (lead antimony,tin) so you might need
to add some high antimony lead to the mix.
The range is indoors, so the lead is dry and free of contaminants other than
paper circles.
We do not usually permit copper jacketed bullets, but there might be a trace
of that too.

E-mail me and I will put you in contact with the guy in charge.
