OK, found it, from 2005:
From a 30-06, 165 TSX on left recovered in wet phone books at 300 yards, impact velocity just at 2,280-ish fps. 165 TSX on right recovered from a 6pt bull shot laying in his bed at 50 yards. Muzzle velocity with both was 2,880-ish fps.
Based on my test, I decided the 165 TSX from the 30-06 was no more than a 400 yard bullet.
Back to your original point, I think you're right. If in fact the test a couple posts back was done with reduced velocity loads, it can't be considered an empirical test.
