I am buying 92-6-2 from a reputable source. Probably many of you are getting it from the same source. I can not seem to get the trash out of the lead. I have fluxed with beeswax, pine saw dust. It shows up in the bullets no matter what I try and seems to show up worse at higher temps. Sometimes worse than others. Amazingly to me it seems to get better as the pot gets near empty. Does anyone have any suggestions?
