I was sittin' round wonderin' about bullet alloy hardness the other day. The question came to me, if 20 - 1 lead/tin alloy is BHN of 10 according to some info I had from Lyman, if you took WW alloy and made it the same BHN as the lead to tin alloy, would it expand like the 2 ingredient alloy or would the ww alloy still be a little less ductile than the lead/tin alloy, considering it has more "stuff" to make it not as ductile, in the mix of the ww alloy? Or is BHN 10, BHN 10, regardless of the mix used to get there?
