Be on the lookout for a steel or cast iron pot to melt your lead in, instead of the aluminum one. Aluminum gets really soft at the temperatures lead is melted, sometimes the bottom falls out of the pan, not good.
By all means keep the small flow of lead going, but you will find the .44 mag will take a lot more than that.
I started with a Coleman stove and the first pot I used was an aluminum sauce pan, then I read of a few misfortunes with the aluminum pan and went to a cast iron one pint sauce pan with and a small soup ladle. It worked, sort of.
Later I found an RCBS lead dipper, it has a fin on the bottom that makes skimming a clean hole to dip from easier than the round bottom of the Lyman.
Later still I bought a Lee 4-20 and could hardly believe just how much easier it is to cast when you don't have all that heat radiating from the hot container of lead.
Good luck and be careful,
Robert
