Use the Special Materials prices aside from silver because they gave the silver bullet a new ability (auto confirm crit)
Adamantine: +60gp per missile (75gp)
Cold Iron: Twice as much (30gp)
Mithral: +500/lb (about .5lb/30≈.02lb .02lb*500gp/lb≈8.33gp; 8.33gp+15gp=23.33gp)
as far as the silver goes I would just add 14gp to the bullet price for a cartridge (the regular bullet inside was 1gp of the 15, so you take that out and put the silver price in) so 39gp
