For a large frame hunting revolver, my first pick would be a Ruger Super RedHawk in .44magnum or maybe the .454 Casull.
Magnum Research's BFR line is good too but they are single action. The .45-70 is impressive.
Taurus has the well made Raging Judge series. You can safely fire the .410 shotshells, .45LC or .454.
If you buy a BFR or the SuperRedhawk revolver, I'd add the Mag-Na-Port or Hybraporting, www.GeminiCustoms.com
. It will reduce the muzzle recoil & may help the DA revolver feel more balanced.
