Of the two pics that you posted hardcast, I'll take the Weatherby. To me, that TC is just flat UGLY! I'm definitely old school.
I'm also sure that the 6.5 CM is a great cartridge, and if I hadn't bought a new .308 Win a couple of years ago, I might consider buying a 6.5 CM. But with a .257 Ackley, a .308 Win, .270 Win, etc, I see no need to jump on the 6.5 bandwagon.
In 50+ years of Colorado and Montana elk and other big game hunting, I've never seen the need for a 400+ yard shot. And although I've killed elk with my .257 Ackley, even if I had a 6.5 CM, I would still pick my .300 Weatherby or even my 7mm RM over those other two cartridges for an elk hunt.
