Contamination ???

Boolit Mold Join DateMay 2013Posts13

Anyone know what causes this contamination? These are the worse examples, just to get a good photo. I'm using a Lee Pro bottom pour, Lyman 175 TC die. Is it something in the lead, or the cavity? If I open the mold and look it's there before I drop.

Thanks

Looks like inclusions. I'd remelt and flux a couple more times. Be sure to scrape the bottom and sides real well. I'd empty and clean that bottom pour, too. They have a habit of hanging on to junk at the spout.
