So I have about 300# of nice clean lead cable sheathing to turn into ingots. I also have a good supply of pewter, about 30#. Was thinking of making ingots of 30:1 (lead/tin) because this is about right for moderate loads in my .357 and .44 revolvers. When I want to cast for moderate loads in my 30-30 and .308 I can add lino type to theses 30:1 ingots. Is this a good plan? I know some prefer to make ingots of pure lead and adjust hardness when they cast.
