I think some are getting lost in the difference between cartridge, and firearm! For me the 357 is never going to be extinct because it can do anything the 38 special can, but it is a 357. Some may not know it but the 38 special as well can do anything the 357 can do,, for the advanced hand loader! But the firearms they are both made for determine the way they can be used, not the other way around. The real difference would be in what a chief's special will take, and what a Redhawk Blackhawk or even a Speed Six will handle.
This is why it will never die, but I just can't wrap my mind around considering it as a big game cartridge,, unless one think a deer or a blackbear is all the same as big game,, if they do trust me,, Elk and Moose are in another league, and for me would be out in favor of bigger projectiles., and they are not as big a game as many use handguns for. For me it as at best a small game to medium game cartridge in real world hunting.
