Sverre - actually, I was going to ask why you would want to do that. The 9mms are basically undersized for the bore (.355-6 vs .357-8), and the 357 is so much longer than the 9mm that you will get a lot of jump from the end of the case to the rifling, which is liable not to grab the bullets enough to impart any spin or accuracy.
A lot of fellas feel that with the advent of all the inexpensive surplus 9mm ammo some sort of modification to a current handgun will allow enjoyable shooting of inexpensive bulk ammo, but I think two operational issues here are the cost of the modification and the concept of enjoyable accurate shooting.
I am willing to bet that the difference between bulk 38 spls, wadcutters or otherwise and quality bulk 9mm surplus is pretty slim. Lots of 9mm surplus is not great quality. In addition, the 9mm really doesn't give you any advantage in a revolver. I don't know why the hay S&W chambered a snubbie in 9mm - Gila Hayes, one of the Editors of Women and Guns Magazine once opined that the pointed nose bullets of the 9mm sure made for easier and quicker reloads but for that lady I would just have soon have advocated for a round nose flat point 200 grainer in 38 Spl as a more effective load with the same bullet profile. Ah well, at least they're shootin'. JMHO. Mikey.
