CCCC, IIRC, TW took a Dall sheep with a 6.5x55. And he has written of his fondness for the .257 Wby. I'm sure he also has enough grey matter to realize that the "canister size" ,as Bob puts it, between the .264 WM and the .257 Wby is not that great and that .264 bullets offer even more ballistic potential arguably than the .25s.
These guys write for groceries so any observation, opinion, expectation, or even an aspect of one of these they have is fair game for an article. It's probably still accurate to say that in the States the 6.5s are outside looking in despite the .260 and the 6.5x284 and their adherents. And the old dog, the .264, in the right platform (no 24" tubes) while excellent is not exactly common.
Relax; it's just an article, not a something he is trying to get accepted into the canon of Scripture..
