Pete00, I glad to be of help.
The sad fact is, that since the advent of commonly available, reliably expanding, jacketed bullets. Both hollow point and soft nose. We have lost a lot of info on the qualities of cast bullets. Sites like Castboolits brings that knowlege back to life.
Now to your specific issues, in the .357 magnum, a cast bullet can be driven very fast compared to its jacketed counter point. A 158gr jacketed bullet from a 4" bbl is going to make 1200 to 1275 fps. It's lead counter point can easily make 1300 to 1375 for the same pressure. The lead bullets friction is much less than the copper jacket.
Alliant 2400 is a good medium to maximum .357 mag powder. Regular or mag primers make it work.
H-110 or WW296 use only mag primers and should only be used at max levels.
Goodluck and enjoy the new revolver.
