If lead gets too scarce to be economical, I think that jacketed mild steel is the most economical alternative for a big military. Don't know how that translates to boollit casters.

Maybe small CNC lathes cranking out precision turned mild steel cores to be fitted inside spent 22 casing brass?

Still, there are very few metals that have the characteristics that make lead such a good projectile, although Bismuth has taken over for "lead free shot" in some loads. I don't see that as economical though.
