No melting down toy soldier for bullets anymore.........the alloy is wrong.  Given lead poisoning laws in the industrial nations all those figurines are pewter.......

Pewter bullets?  Are they even functional aside from the thrown rock impact that is.  Would pewter make a good hollowpoint?

Pewter is some hard shtuff. It's 95-98% tin if you're talking Britannia Alloy (food-safe pewter) as opposed to the leaded pewter. I have only heard of the leaded alloy, I've never seen it for sale. I doubt it would expand much and it's pretty light weight so it won't maintain lethal velocity. I have a small supply of scrap pewter that weighs less than a lb total. I threw one piece of it across the garage with the only result being my ears hurting from the clattering ping sound.

If you're going to use pewter in an alloy, I know it is often used in bronze as a tin source by backyard smiths. It gives the bronze hardness as copper alone is not good at retaining its shape with heavy use.

Given that pewter is mostly tin and tin is often alloyed with lead to harden bullets, I suppose the questions would be "what else is in pewter?" and "how much pewter would one add to their lead to get the right alloy for their bullets?".

The rest is Antimony and Copper. The Tin content varies from 92-98% with mostly Antimony making up the remainder.

I cast my own roundballs for my muzzleloaders, and also 12 ga. slugs, out of wheel weights. They work fine for me. But, how do you tell the difference between the zinc weights and the lead ones?

Look for the 'Zn' marking.  Or take a tin snips to the wheel weight.  If you can start to make a cut, it's lead.  You can also do the 'tap on the ground' test.  It's hard to describe the sound - lead sounds dull, zinc, not so much.

Ugh.  Did some searches on ebay for tin ingots.  Stuff is $10 a pound!!  Granted one only needs 5-10% of tin for casting but still...

Think I'll concentrate on flea markets for pewter.

The harder the metal, the more it will ring, and the higher the pitch will be.

Old solder is often surplussed out. Electronics grade will usually be 63% lead and 37% tin, way more tin than necessary for bullet alloy. Companies trying to get RoHS compliant (pronounced row hoss in geek speak), will be glad to get rid of it.  The flux in it will help raise the dross. If you run into a company changing over a wave solder machine, you'll hit the jackpot.

Hmm... I'll keep my eyes and ears open.  Thanks!

Try not to end up with radioactive stuff. Metals from the former USSR have been found to contain Strontium 90 among other assorted nasties. This is because several deactivated reactors have been hit my metal thieves who sell the scrap to scrap yards without telling them where it came from. So that cheap ebay deal on sheets of Russian lead? Don't risk it. I stumbled across this info while researching bioremediation of radioactive wastes. Lead can be radioactive if it is a byproduct of fission. And this stuff is usually stored by burying it. It's also possible for it to be contaminated with particulate which ends up in any scrap lot it gets melted into. If you have stock of metals from there already, I suggest getting the Geiger counter out of your BOB and making sure you don't have a hot batch sitting in your workspace.

Yikes.  Thanks for the info.

But think of the type of bullets it would make?
Just right for some JBT turd.

If you aim well, it would be irrelevant to your target, but roughly equivalent to pulling the pin on a MkII Pineapple and sticking it in your pocket. You could hurt your opponent, but are more likely to just kill yourself by handling the stuff or carrying it around. If you failed to recover it and it contains the stuff with the longer half lives, you could poison someone up to a few billion years later.

Yes actually. I would not mind being immortal. But there is a question in my mind of whether or not death is even possible in the sense of a finality to life.... Isn't existence really a dance of light and dark, life and death... No energy is created or lost, nor does any new matter come to exist or pass away... All things are simply in a state of constant change. And by that token, none of us truly ceases to exist... We simply change form. Like the day passing into night, the Sun rises again in the morning, and so rolls the wheel of time... We are born, we consume dead things to sustain our lives, and then we die and are eaten by other living things, and become their life... So we are dispersed and come together again in different combinations, but our energy and matter are never lost... All of it is simple rearrangement.
