BHN Hardness for 10MM loads?

gofastman, that alloy should work out to be about 97% lead, 1.5% antimony and 1.5% tin.  It should have a BHN of about 10.5 air cooled, and about 16-18 water dropped.  Running hot enough for frosty, small bullets you might get that bhn into the 20's, especially if the pewter is one of the varieties with some copper.

Yeah, that sounds about right, yes there is a trace of copper in the stuff I'm using.
because I cast hot (very frosty) and like to smoke my molds, most of them were designed about .001-.002 oversize
