Re: Powder recommendation for 125g. 357 please.
My favorite 357 loads (125 JHC and 158 lead SWC) both use WW 296. You could also use H110. It is the exact same powder. Takes magnum primers, though. 18.5 grains with the JHC. Got that data from on old Winchester book. The Hodgdon site gives a heavier load, I believe, but this one works for me.
