I need to change the lead completely in an RCBS ProMelt and a Lyman Mag25. One pot is contaminated and the other is a complete mystery mix. I just want to start from scratch with a known allow of known good lead. I got the pots on a deal and I don't want to make it a "He chose poorly" story.
The issue is obviously that draining a pot is a great way to clog the spout...causing an absolute nightmare. I saw this happen once. Does anyone here have experience and good advice on doing a changeover?
