If hunting from a stand AR rifle's will give many more choices IMO, .300 AAC Blackout would top my list. The .300 with 125 grain bullets will put you in 30-30 territory for range and power out of a 16" or longer barrel. Plus there are a lot of other chamberings to be had, many already mentioned.
Now if you are out walking around I'd rather carry a lever action rifle. I would look for one in .30-30 or .35 Rem over the .357 Mag. Look to Savage or Remington for a good lefty bolt action.
