Obviously you do not take into consideration big game/ dangerious game hunting with a revolver.
Had you, the 445 Casuall, 460 S&W, and 500 S&W would have also made the list. Although my own biggest wheel gun hunter is a 44 Magnum Super Blackhawk, I certainly wouldn't throw away those three big boomers as not being useful revolver rounds.
Those guns go beyond my concept of a handgun. They require a revolver of such weight and proportions that a rifle or carbine is better suited to the hunt.
I'm not putting those guns down, but they are as practical to me as having a .505 Gibbs or .475 Nitro Express in my battery. They just fall outside my parameters of a handgun.
