I have a box of ball mill media I would like to use for bullet casting.
The guy who cast it up 10 years ago or so told me he started with pure lead and just added lino untill he thought it was hard enough for his purposes when water dropped. His only hardness testing was to see how easily it cut/scratched with his pocket knife- He wouldn't even hazard a guess at the final proportions.
Anyone got suggestions on how to go about characterizing this alloy? I don't yet have a hardness tester. The fact it will harden when quenched and the alleged ingredients make me think it's worth the time to work with this.
