OK, just set up a new burning setup with LNP and basically, not really into it. Aside from the fact the 20# pot will have to rest on a heat diffuser to stay above the burner, I really have no business using the LNP - I used to brew in a 20 gallon 3-vessel brewing system I built and the CO output, even outside, used to bring on explosive migraines that scared the hell out of my family they were so bad. Broke out in massive sweating, etc. Dumb decision.
Anyway, not ready to commit to the RCBS Pro furnace. The Lee Magnum melter seems at least a reasonable compromise, given that I dipper-cast. Unless it's not regarded very highly. Anyone use it, and have thoughts about buying one (I don't load heavy, maybe 100 or so rounds every few weeks or so).
