Lead Free reloading

I need to reload 38 + P out of a 357 gp100 . The only alloy I can get my hands on is 88% Bismuth, 12% tin. Is anyone familiar with this?
1)Will this be so hard that it could hurt the bore?
2)Does bismuth expand during cooling (what diameter of mold would be used if so?)
3) I saw some nickel coated 000 shot (I know this has a lead core, but would love to use this in self defense loads (not on the range) using two shots per case), anyone know the effect nickel would have on the bore?
thanks for your help

why do you have to have the lead free? just curious.

cant help you with the bismuth, but the buckshot is lead that is nickel plated, much like copper plated lead projectiles, I doubt it would hurt your bore, but that is lead, as in 99.999% and maybe 0.001%nickel, plating, if even that, hence the question, whats wrong with lead?

ahh, I should have guessed it, cant help you with the California rules, or the gunrange for that matter, but the 000 duplex is something I was about to experiment with myself, kindof senseless to make them for self defense and not be able to try them out or practice with.

all I can say about other alloys, maybe look at material hardness data than compare it to lead, I read a post recently about casting zinc bullets, it was referred to as very similar to shooting jacketed so jacketed rules apply
