Practicing revolver reloads with cases shorter than you would be using in an actual situation may give you a false impression of how hard it actually is to get long cases to completely clear the cylinder.
Whatever you decide on as far as reload-training, be sure there are no dainty or deft movements required.
It can't be repeated enough:
Fine muscle control goes to hell under stress.
If I had to reload a revolver with just one hand, and that hand being my weak hand, I think I'd come up with some sort of movement that involved going to the ground, because you WILL fumble rounds doing that under high stress.
Many moons ago when I was professionally trained for stress-reloads of a revolver, they trained us to just get two rounds in the gun during the reload, and then come up firing.
Those were the days of the "dump pouch."
