I'm interested in buying a revolver large enough to try and hunt moose with, while also being able to carry it for bear protection on occasion. I've been primarily looking at either the .454 Casull or .44 Mag. I have never used a large caliber handgun for big game hunting so I have no experience in this matter. What would be the best option. I don't need a bunch of excess power, but I would rather be safe than sorry. Any helpfull recommendations and advice would be appreciated. As a side question, I kind of liked the advantage of being able to shoot .45 Colt through a .454 Casull. Does this do any excessive wear to the chambers, throat, barrel of a .454, or is it perfectly fine?
