As Selections get scarce, just for fun I loaded up some 9mm(.355) bullets in 38spl. cases.
Shot 'em out of my python.no difference at all in poi.Dont know if I'd put .357 in a 9mm,hmm, anybody done that?
I have loaded 158 berry's in 9mm cases. No real difference to 147 grain. There can be some problems with some pistols that have a short chamber. S&W M&P is shorter than most.
