Hello,
I'm new to casting (been reloading for 20+ years) and I want to cast for my 45 colt and eventually by 30-30. Also, I just bought my first batch of lead from here. It's not pure and mostly wheel weights. So, my question is what mixture should I use to get a mix that is hard enough for a 1200 fps load? What hardness should I strive for? I don't plan on using gas checks and I plan on pan lubing the boolits.
Thanks for the help.
