I gotta say, with all this talk about pushing a revolver to it's maximum limit, perhaps just a bigger gun-designed for the intended power-is needed? Lots of ammo manufacturers load great bullets with moderate or even reduced loads of 454 or 480. Even better if you hand load.

And really, many a wise handgun hunters of bear will tell you that moderate speed is best. Big heavy bullet, yes; max powder underneath, nope. The thing about snubs though, is in order to get a moderate speed, you've got to use a max load. I guess you know where I stand on snubs. But you do you.
