The little .338 Fed is a good round but lets not get carried away extolling its virtues. We are still talking about the .308 Win case after all, which has considerably less capacity than any 7 mag case. Its a real stretch to say the .338 Fed has more energy than the 7 mag. Only if you compare the hottest possible max pressure load for the Fed to a pedestrian load for the 7 mag. Load both to max, no way.
