Tin or Antimony

Anyone know of a source where a guy could get some Tin or Antimony to alloy with lead for casting bullets.

Printers type would work also, I just need to harden the lead that I have up some so it won't galled in the barrel, plus I'm having thoughts of building a 1780's period long rifle so will need fodder to feed it with.

I've got a few hundred pounds of type metal, I'll pack some up in the box I'm putting together for you. How much do you need? Don't use this as is, it's way too hard for bullets. I've seen formulas online for mixing Lead, Type Metal and some extra tin solder (Pewter) for muzzleloaders. I had a 357 once and got some bad soft bullets. Fired about 3 times and then couldn't hit the broad side of a barn. I looked and had no rifling visible. I took it to a gun-shop and he sold me some copper jacketed and told me to use these. One shot and I had rifling again. :)

This will be closest to slugcasting alloy, 3-4% Tin, 10-11% Antimony, and the rest Lead.

had a friend give me about 10 pounds of lead pipe, that I'm wanting to use to make bullets for the Winchester. I don't know the alloy that's used for type, but I know the tin helps with the casting and the Antimony makes the lead hard.

I'll leave the how much up to you, how much would you use in 10 pounds of lead?

There's probably as many alloys for bullets as there are people making them. I know I don't want something that will lead the barrel which can happen even if you use gas checks.

What little I've read about it, you should have more Tin than Antimony and neither one over 5%. There are many formulas, if you have some way to test hardness, that's the way to go.

I did some looking on Ebay, but wasn't really impressed with the prices as in the link you provided wanting 19.00 for a pound plus shipping.

If Jerry has some old type that he would like to get rid of a couple pounds I would rather pay him for the metal then someone on Ebay.
