I am looking to use my 500 S&W to take my next moose or bear if conditions are right (I'll also have a rifle). My question is which bullet will be better to have loaded. I understand the general consensus is hardcast over soft points when it comes to bringing down large game, though I wonder if that holds true when the soft point is 500 grains and will probably still have no problem penetrating plenty. Could the XTP have better 'smack'? These are big and can be dangerous animals but they still have relatively thin skin. A possible bear would probably be interior Alaskan grizzly or black, not the 10' kodiak browns. The revolver model would be a John Ross 5" with 1:12 twist. Loads would be moderate, about 1100-1200 fps for the 500 xtp or same for a 500 HC or 1200-1300 fps for a 440 HC.
As a side question, does the faster twist of this revolver model affect terminal performance at all?
