It looks like I will be getting access to a magma bullet casting machine for a few hours. All I have to do is supply the lead and do grunt work. I have zero experience with these, but there will be somebody there that knows what they are doing. I am most likely going to be running some plain old fashioned bullets. No hollow points or anything else fancy. As it stands, I have plenty of .38 bullets. And about the only other things I am going to need in any volume are 9mm and .45. So for just plinking bullets, what alloy should I be looking at for this machine? The pot holds about 40 pounds, and it can crank out a thousand bullets in an hour. And I don't want to run my normal mystery scrap lead through somebody else's machine and screw things up. And where should I get the alloy from? Right now, it looks like Brownell's has the best prices on 5 pound ingots for things other than pure lead. But I am loathe to pay retail if there is a better source. What does the hive mind recommend here?
