Say on whitetail deer ,which of these to calibers is better . Is the bigger 500 going to really out do the 454 Casull ? Just want to get some opinions. Of course I just bought a Raging Bull 454 a couple years ago thinking it was the big boy around these parts ,is this just a gun to buy to say I got one bigger? I will probably stick with what I have an let someone else keep up with the Jone's.Besides my wife would use it on me if I spent that much on another toy right now ! Of course the recoil might get both of us!
