Now there's a thought
Truthfully, I just retired and am more interested in playing around with this sort of thing. Many years ago, when I was shooting bullseye a LOT, I cast with 2 10# pots, 2 - 4 cavity molds and sized with a Star. Regret selling the stuff. Could easily cast 1,000 in an evening. Pretty sure I do not want to go that route again, but Lord only knows where my mind and ambition will take me. My buddy is a commercial caster, and his 45s drop at .452" - pretty consistent.
