You may have come up with the best expanding cast bullet alloy in the world at 1800fps and 100yds, but be faced with blow up at 50yd and penciling through at 150 - 200yds.
So, for those reasons alone, I say the BEST cast bullets with a good WFN -meplat - begin at .35cal and get better as the bullet dia. increases.
With my 45/70, 465gr an .460 dia WFN, I not only don't need expansion, but simply do not desire that unrelyable situation to occur.
So for me, I'd hang on to my RUGER #1S - 45/70.
