I have 6000 lbs of range scrap that are smelted in to ingots. I want to cast that in to bullets for 9 40 45 38 so and 45/70 . I am new to casting I just got the magma caster. What I am wondering is foundry lead the best mix to use for 92/6/2 . The rate that I have figured out would be 10 range scrap to 3 lbs of foundry . Any help would be appreciated thank s.
