The .460 Weatherby is powerful, all right...but nowhere near the most powerful shoulder-fired.
I think this one takes that prize:

A standard (non-explosive) round has some 39,500 or 40,000 ft-lbs of energy. The Weatherby? around 8100 ft-lbs. The .50BMG with an 800 gr (half the size of the 20mm) bullet has about half the energy, just under 15K ft-lbs.
