Recently remelted a LOT of old bullets I'd cast over the years along with a bunch of old Telco sheath.
Anyhow I had a fair amount of dross left when I got done so wondering how much metal was in it I heated it up today. Interesting.
6.20 lbs of dross yielded 2.37 lbs crud and 3.8 lbs of metal. Dross was basically powder as it was likely mostly unburnt bullet lube from those old bullets.
A comparison of a ingot of bullet alloy weighed 15.3 oz while a similar ingot of the reclaimed metal weighed 13.3 oz.
Suppose there's quite a bit of tin in those new ingots?
