Only time I've seen this done was to overcome flinch. A guy I knew was flinching badly with .357s and to combat it, he would load 5 .38s and 1 .357 and spin the cylinder before closing it. He never knew where the .357 was, but having 5 mild .38s was easier on his nerves. He did it for several range visits and finally overcame his magnum flinch. But, he was not carrying the gun at the time.

I'd never do something like this with a carry gun.
