Is there a Lyman #3???

[cwlongshot]

I have acquired a good supply if ingots. Smelted by unknown source.

There is a large quantity of bars Some are marked LY#2, COWW, SOWW/Lead, BISMUTH & LY#3. Just a few Bismuth and most are SOWW/LEAD.

I have Never herd if #3 as a "hardness". Do anyone know what this might be?

Any help appreciated. There is only a small qualtity of these maybe 25 bars but wont waste it!

Thanks guys

Lyman #2 is harder than #3, but of course I can't find the ratio, online.

Ideal #2- the 90/5/5 alloy commonly called Lyman #2 today.
Ideal #4- 1 in 20 tin/lead alloy.
Ideal #6- 1 in 40 tin/lead alloy.

#3 alloy was 1 in 10 tin/lead alloy. #1 was 80/7/3/10 lead/antimony/tin/copper [the % of Sb and Sn varies with source].

Thanks for that info, Larry. Dang, with that much copper, that #1 had to be one hard alloy.

Yes, #1 is a very hard alloy. It was considered the "standard" alloy for numerous Ideal bullet moulds for use in 30 - 8mm rifles, mostly military, in the late 1800s and early 1900s. Also, #1 alloy gave considerable shrinkage which is why many of those earlier Ideal moulds will cast .002 -.004" over nominal diameter with #2 alloy or linotype.

Thank you everyone!!

The #3 rings more then thuds but no where near the ring of the #2!
