Since Bismuth loads are stated in weight and not volume I have always used an adjustable bar or a modifed mec bar that throws the desired of weight of Bismuth. I have never heard of anyone doing otherwise.
An equal weight of bismuth to lead is going to have a taller shot column.
PS. I am pretty certain Sherman weighed his Bismuth loads, the evidence is the difference in amount of filler wad needed for the same weight loadings vs. lead.
