it is doable but not a good idea at all.My opinion only.

We are a licensed manufacturer and have our own stretch frames and oversized medium frames. We have almost 70 of our own cartridges, the 475 GNR being one of them. But I will not chamber a rifle cartridge in a revolver. It would be screwing you. A rifle cartridge has to be loaded with rifle powder, which will not burn well in a revolver. You would get a lot more power out of a 475 Linebaugh than you would our 475 GNR in a revolver. An 8 or 10 inch revolver can only burn a certain amount of rifle powder. The rest goes up in a bright flash at the end of the barrel when it hits the oxygen. The revolvers chambered in rifle calibers, or at least the ones I have seen chrono'd were a big disappointment to the shooter. Much less power than if chambered in a rifle barrel.
So it can be done, but I sure don't recommend it.
