dal, that's why I asked, specifically, about hardness. And bismuth manufacturers DID recommend the direct switch years ago when Bismuth first came out.

old colonel, if I load by volume then a "1.5 oz" will actually load 1.3 oz of Bi using the same shot bushing. If hardness isn't an issue (as with steel) think, I'll be pretty darn safe if I stick to the same volume of Bi instead of the same actual weight which would be hard to fit in the hull for most loads. There certainly isn't a lot of information out there. I found BPI has a reloading manual specifically for Bi, but it is out of stock.
