Even if bullet weight and velocity are relatively equivalent, a bullet that is loaded into a revolver does not have to feed through magazine feed lips, then, if applicable, bash into and then climb a feed ramp, and perhaps bash into the top interior sidewall of the chamber, before the cartridge is seated into place. The Federal Hi-Shok 125-grain .357 JHC, that was in the chambers of my GP100, one fateful night in 1993, looks nothing like the 124-grain and 125-grain ammo that I now load into my 9mm Glocks.
The 180-grain ammo, that I load into .357 revolvers when four-legged opponents are part of the day’s threat profile, not only looks far different from any 9mm I have used, I do not believe that there are many, if any powder recipes for what little space would exist inside the case, if that long bullet could be loaded deep enough into the case for a correct OAL to ensure feeding, even if the blunt nose profile would feed.
