When using a 357 for hunting you should just know what its limits are. This weekend my nephew used a FA`s mod 83 ( which is the exception) with a handload pushing a 180gr XTP close to 1700fps to drop a small body Corsican with one shot to the chest.
However, I once used the same gun/load to hit a 4 horn in the shoulder as he 1/4ed towared me and the bullet blew up on the shoulder bone.However, this weekend I used again used this FAs combo to take a small bodied mouflon with a shot that was a little to far back but because of the velocity and XTP it downed the animal. If a normal 357 was used I doubt that it would have had the same effect. I think Jeff Copper put it best when he stated what his formula was for handgun hunting:
1) no less then .40 caliber
2) no less then 200grs bullet weight
3) no less then 1000fps
