Does anyone get perfect boolits out of this mold? Been casting some really nice ones with the exception of the tip of the HP. I have a 452 HP mold that fills in nicely but the 356 has a thinner longer cavity to fill. Not much lead in the cross section. My molds hot, extra tin, extra heat. I'm only talking about 15 thou at the tip but curious if anyone get 100% fill on these.
