An optimally hard lead bullet is simply one which obturates at a given pressure sufficiently to seal the bore against the gases which would otherwise “cut through” the soft lead (called “gas-cutting”, forcing molten lead into your rifling. A bullet which is too hard won't obturate and seal the bore, because the gas pressure is .
I made a spreadsheet that will let you calculate the properties you get when mixing two or more types of lead. Let me know if there is anything that is incorrect or needs improvement.
