After getting wheel-weight lead for free for most of my life, I've had to resort to buying it.
Our local auto-scrap yard charges forty cents per pound.
I normally buy 100 lbs at a time ($40.00), a couple of times a year. After sorting out the junk and zinc, and melting it into ingots, I end up with about 80 lbs of good wheel-weight lead from a 100 lb bucket of scrap wheel-weights.
80lbs X 7000 grains = 560,000 grains of wheel-weight lead
560,000 grains divided by 200 grains per bullet = 2,800 bullets
$40.00 divided by 2,800 bullets = .0143 cents per bullet.
Bullet lube is less than $2.00 a stick from White Label Lubes (excellent stuff!)
A stick of bullet lube will do about 2000 .45 ACP bullets.
Total cost = less than 2 cents a shot including the propane used to melt the lead.
By the way, I'm using the bullet casting equipment that I purchased in the 1970's.
Yes, casting bullets is working nicely for me.
