I'll have a shot at this.
I need my 45's to be pretty soft so I just towel drop those. My 9mm has to be harder and they get tossed into water.
If you have different lead types, you'll want to keep everything separated until you figure out which caliber is going to be cast. Might want to skip the small, gas checked bullets until you get some experience.
Start with one, master it then work on others.
If my pot is ready to go, I can make about 300 9mm in an hour with a lee two-hole.
