that stuff is expensive.

What's another good source for free lead? No tire stores around here give out free tire weights, even if I did say it's for a science project.

Try the backstop of your local airgun/black powder range.

also cheap wallmart fishing lead weigts

How about buying it from a scrap dealer, probably around 10 bucks a kilo.
That's not toooooooo expensive.

If you want to play it dangerous, you can get a few pounds of lead out of car batteries. You'll need corrosion resistant gloves, goggles, and a resperator, preferrably.

DEAD ones... By the way.

Go to a scrap yard, lead is only about $0.50USD/lb last time I got some. I was lucky enough to find a deposit from a caster (probably a reloader) in nice ~.5lb ingots that fit perfectly in my lead pot. If you are lucky, there will be some bullets there as well. I got some that are about .64 cal, they look to be for a muzzle loader. They melt nice and quick in a half full pot of molten lead, without freezing their surrounding. Great for when I am am casting a couple pounds of ball mill media. Hell, the bullets them selves would be good media...

it deforms far too easily upon impact to be terribly useful

he is refering to lead....

Expanding hollowpoints anyone?

i was wondering, could i use cement as the mold and use solder as a projectile? or would the cement break and the solder be to soft?

EDIT- i think i would like to make a bullet shaped projectile, would that work too? i was going to make it for 1/2'' pipe

I want to make a bullet shaped too but remember that you dont need 2 pieces of plaster for that
my father has that caps you put in front of your mouth and nose. would they help a lot ?

and am I helping if I say you maybe can make a mold for multiple balls ?
and I want to skip the wax part and use a marble since i have a marble barrel.
