I absolutely love my 338 RUM. I wouldnt go elk hunting without it. I load my own 225 Swift Siroccos and practice with that gun out to 500 yards. We set up multiple targets and even measured groups for averages and made up cheat sheets. Some people might laugh but when your out hunting big game and they are out 4 or 500 hundred yards, you dont want to be debating on how high to hold. We laminated the cheat sheets and taped them to the stock with clear ducttape. If you take your time doing it it doesnt look bad either. Kinda off topic a bit but just saying that if you know your gun well enough and are confident in it, it is worth taking the shot. I would take that same shot with my 7mm RM.
