Another thing to consider in reloading 9mm for a revolver is the concept of possible "bullet jump" in the cylinder, supposedly due to the 9mm case rim being held by the moon clip and the latter rounds being exposed to recoil multiple times...? I've seen it argued that the 9mm was not originally designed for use in anything other than a magazine-fed firearm.
Proper (i.e., minimal) expansion and a good crimp should avoid this problem. I like the LEE FCDs for all my reloads.
Cheers!
P.S. Ruger even goes into this concept in their manual, so it may actually be relevant: of course, testing your firearm with various types of ammunition for reliability is always a good idea, regardless of caliber. They also warn about using ONLY metal jacketed bullets (and none of them NASTY reloads, either!) because of possible lead build-up in the chamber (Uh, wouldn't that be the cylinder?)...
P.P.S. Wish someone would come up with a 357 SIG revolver...
