Hello all:
I've just wrapped up a run of 44-250-KT boolits, which came out pretty well. Still a rank beginner, these bullets may put me at close to 200 projectiles.
I am using wheel weight ingots I bought off of EBay, so I really don't have much knowledge about how they were smelted etc. The guy sells a lot of alloy, and seems to have a lot of good feedback there, for what that's worth.
I flux using Midway's powdered flux, which does create a little filthy looking scum, which I discard. Quite soon, however, the top of the melt has a film floating around that reminds me of aluminum roofing paint. It collects on my ladle, generally looking like crap. If I skim that stuff off, its back in a few minutes.
I finally quit worrying about it while casting, and the boolits look fine, but I still wonder what this stuff is, if I should worry about it, if I should do something differently, of if something may be wrong with my alloy.
Any insight is greatly appreciated.
Thanks
