Set a video camera on a tripod, and film the test firing.
It will help a lot, when they try to figure out how you mangled your hands, in the event that you bleed to death.
That others may learn, and all that, eh?
Somewhere between a bad, and incredibly stupid idea, even on the odd chance you have a rimfire with a long enough cylinder to convert. They simply were not built to take the pressure.
Irresponsible stupidity to convert it and say that you will "only ever shoot reloads at appropriate levels", as you will not be there to stop anyone that picks it up and in their ignorance, hurts themselves or others by loading ammunition much too powerful for it.
