Well, the good Col. Whelen did say, "The 30-06 is never a mistake." and I'm inclined to agree. I've shot a lot of deer with the 06 over many years and even took one cow elk back about 4 years ago with the 06 running a 165 gr. Accubond. The elk ran about 30 yards a collapsed. One the other hand, most of my elk hunting (cows only as I just hunt for the meat.) have been taken with my .35 Whelen and the Barnes 225 gr. TSX at 2710 FPS out the muzzle.
Results with the Whelen on 6 elk were 3 bang flop, DRT and 3 bang flop, couldn't go anywhere but needed a finisher. Elk were shot from 75 yards out as far as 350 yards. It's worked so well that I haven't bothered to try any other bullet in that rifle.
