I have been casting several times, using the same 2% tin - 5% antimony - 93% lead alloy each time. Since the bullets aren’t turning out with the quality that I want yet (but I’m seeing improvements each time I cast), I just place the previously cast bullets back into the pot for the next session.
I am fluxing with cedar mulch, that I originally purchased for pet bedding. This seems to work pretty well - at least, I’m getting dross from the fluxing, and the surface of the molten metal is bright and shiny after fluxing.
My question is, since this is a pretty low percentage of tin to begin with, am I likely to be losing enough tin during this "cast - remelt - recast" process that I should add some tin to the alloy? I’ve wondered if part of the reason for the incomplete bullet fillout that I am still occasionally seeing is due to the tin content being too low. Opinions?
Thanks,
