Alloy composition

[DocSavage]

Purchased 56 lbs reclaimed bullet metal from Rotometals 94% lead and 4% antimony I plan on adding 1 lb of tin and a couple of oz of lynotype that's I stumbled across. I'm figuring this mix will come in around 12 bhn. What say you?

I'm guessing @ 1.76%Sn_3.95%Sb_94.3%Pb...weight 57.1 lbs. & 12.7BHN.

when you say "94% lead and 4% antimony", do you mean, "94-96% Lead (remaining), 0.23% Tin (trace), 3-4% Antimony 0.17-0.386%, Copper" as stated on Rotometals website?

ANyway, adding a pound of tin and a bit of lino should make a nice casting boolit alloy, that is similar to COWW that has been enriched with some Tin (as many here recommend).

Now with the bit of copper, you'll see your boolits age harden a little higher then COWW, but that bit of hardness may not show up for 5 or 6 months (that's been my experience anyway)

Yes that's the alloy. Figured 1 lb tin and the lino would come in a 1% give or take. I might have some tin solder scraps I can throw in as well.
