I can't see how you could ever go wrong with the 130 grain AB in any 6.5mm cartridge in a rifle with a magazine long enough to handle it.
It is my favorite medium game bullet in long actions, the 6.5x55, 256 Newton, and 6.5-284, and in short actions, the 6.5 Creedmoor, 260, and 6.5 WSSM.
The only reason that I would use a longer bullet is if the rifle had a long/deep throat and I wanted to minimize the bullet's free-bore jump.
Mine too, it works well for me on antelope sized deer in my 260 anyway. I really like the 140 gr Ballistic Tip too. In my wife's 6.5x55 we really like the 120 gr Ballistic Tip for the same sized animals.
