Cast Lead Thread ?

[T.FOYE]

I found I was making good bullets while I was regularly fluxing and skimming off the dross. Keep it mixing. Don't let your top screw on your lee melter wind out too much (less is more).
It's a good idea to have that thing sitting in an oven tray till you can trust it's not gonna dump hot lead out. I did this and it took a while to clean up the mess
(It all went back in the pot but my pride is still recovering)
