The 260 Rem with a TTSX or Partition is good for elk to 900 yards, and a 270 Wby is good a little farther. A 340 Wby is needed for ranges farther than that because it kicks more, so it hits harder.
Your insane if you think that you can shoot any game animal at 900 yards! You will have to hit it and by the time you get to it it will be long gone.
