From the own Weatherby web site, the loads for the 2 cartridges, with the same bullet weight, are within 200-500 ft/lb of muzzle energy of difference (both over 4000 ft/lb), depending on bullet type
Trajectory at 500 yards (for 200 yards zero) is not significantly different either, within 1-4 inches max depending on load.
Retained energy at the same 500 yards is within 200-300 ft/lb of difference (both in the 2000 ft/lb range or more)
I did check on the MidwayUSA web site and a box of 300 Wby can be had as little as $40 or so (around $70-75 for the Weatherby brand)
The 30-378 is $125 a box (made only by Weatherby)
I know, both are a reloading proposition, still.....
Rifles for the 30-378 are fewer and more expensive
My question is.....there is anything in practice that a 30-378 can do that the 300 can't?? Performance differences are justified by the jumping cost??
Is the 30-378 little more than a technical showcase, a bragging right for the brand??
