Re: Hardness of .38WC
For a 45/70, to make the molds fill better, you want between 5 and 10% tin. A 10:1 to a 20:1 mix. If you get a one-pound bar (or spool, but bar solder is cheaper) of 50/50 solder and put it in a ten pound pot, you end up with 9 1/2 pounds of lead and a half pound of tin. 19:1. Oughta work fine.
