Well I finally got my swaging die just right. It is a .357" round nose. I am going to swage some 124gn AFTER POWDRRCOATING. So I will have very nice concentric PC'd .357" boolits.
I molded up a couple hundred boolits to use thinking they were 13 BHN.
Turns out they are 20 BHN. Even if I could use them I don't want to. SO
When I melt them down again how much soft lead (6 Bhn) proportionally would I mix them with to get in the ballpark of 11 to 13 bhn?
And is 12 BHN an optimum hardness for PC'd 9 mm driven at moderate speeds?
Thanks
P.S. If it makes any difference I have a Norico 213 for the gun. Barrel slugs at .356" and the chamber is good.
