I have a good friend who shoots a .300 Wby... Actually the perceived recoil on his is not too bad, but I have only shot it 3-4 times in a sitting. It is devastating on impact with smallish Alabama whitetails, the small doe he got last year was minus a heart and lung when we got to her. I reload for him, but we found a stack or Remington factory ammo on clearance at Wally World just before season last year and he racked up for $13 a box!
And by the way, he didn't choose the .300, but like your case he inherited it from his Dad. Other than that, it is way too much rifle for anything in the great state of Alabama.
