.500 S&W is an interesting beast. There are loads that will take you for a ride but there is also a lot of fairly hot stuff out there for it that is still WAY more comfortable to shoot than things like .454 Casull or .480 Ruger. Those two, when loaded hot, are the definition of full retard. It also helps that even a 4" S&W 500 weighs a lot more than most revolvers do in those two calibers.
