The velocity was, however, lower than what was listed, by 80-90 fps (for factory ammo).
I'm no expert - and don't know if that's typical or not for "premium" ammo but both rifles shot moa and the hand loads*** seemed a little better - but again, marginally.
***This was also a load he had developed over a few sessions that was on the top end of towards the high pressure maxes.

Read the small print!
Weatherby’s are quoted as from a 26” barrel, with copious free bore included.
And chronograph’s have at least 1.0% to 2% instrumental error from one to another. Let’s see, 3300fps x 0.02= 66 FPS
It’s a number, plain and simple, how one number compares to the next, or even the next 20 is what’s gonna matter.
You can therorize, pontificate, and beat your finger tips raw calculating all the numbers out there. At the end of it all under field conditions, with adrenaline coursing through your veins, is it gonna matter that much?
The OP was about a very extreme situation, which I think was driven by some serious mis quoting of misunderstood results, and is far from typical.
