I own many revolvers but there are some I have no use for, the .454. .460 and .500 S&W. They can extend range but I prefer a deer at 20 yards. I am not going to set a rest for long range because deer don't cooperate like that so most shots are off hand with me twisted out of shape. I also do not hunt huge animals. Yet the .475 or a .480 would be at the top for deer. I see no difference between them. Most deer I shoot with the .475 drop right now and if you say your .480 needs more I will beat you black and blue with a feather!
These calibers are at home with deer but there is no animal on earth you can't use them on either.
There is something about the .476" boolit that I can't deny. You can shoot a deer one day and a buf the next with the same load.
