oh a quick alloy check on unkown alloy ingots is simply to just drop it on a cement floor on a corner.
tud= soft/pure lead.
tud-tink= is low tin type alloy some close to a ww sound but a little deeper.
tinkle-clank = ww's or thereabouts.
tonkle-tonk = high antimony.

anyway you get an ear for it.

If you only knew.

I have some 70/30 bar solder. Hardly ever use it. My low tin range scrap casts pretty well for me so I see no reason to use it.

Tin, in black powder cartridges, is good with smokeless powder. It is malleable and shoots well, while antimony only alloys tend to lead. Just an opinion, not "truth".

0.1lb to 1.5lb of pure lead will give you *3%tin. 0.1lb to 1.5lb WW will put you around 3.4%
So if your pour your 50/50 off into 1/4lb bars you would use 1/4lb to 4lb pure lead (3%) or 4lb of WW will put you around 3.2% tin, for reference, easy to adjust from there. (assuming an average WW makeup as .25% tin, 3% ant, and 96.75% lead) that was the last makeup I saw and I am sure it will vary a bit.

Here is an alloy calculator.
I tried to drop the .xls file on this page. I hope it worked.
I put my kitchen scale on grams when weighing lead, tin, etc. The metric system is so much easier work with than pounds, ounces and fractions.

That alloy calculator file doesn't open directly on the thread page but becomes a download. So double click on the attachment to download the .xls file.
Let me know what you think.
