After smashing my old pot from 5 1/2 feet onto solid concrete TWICE, it died. The post is down below somewhere.
So got my backup out (same brand and type, a Lee) and it is amazing how much faster it heats up and stays hot. I was just about able to get ahead of it but that was after 45 minutes and that's my limit.
After that I get "felony stupid" and clumsily and 20# of 700* lead and me are not a good combination. I was able to blow up a pot of lead by adding some water to it--but that's another story.
In any event the limiting factor now is me. And that's OK since I don't have to wait on anything else.
