I've been given by about 10 pounds of lead allow from acid batteries in cast. Lead is very hard. I heard somewhere that there is 5-10% antimony content in battery lead, which is better, than lead-tin allow for bullets (I heard).
Unfortunatly I got no pure lead to compare hardness with, is any simple methods (by finger nail?) to found out the hardness of this cast aprx.?
