I think "want to" is the overriding reason for trying something different; we all rationalize our choices.
Will the results of the 6.5 C be any different than the 308 WCF under the conditions you state in the OP? Probably not.
I've been using a 6.5 Swede since 2004, and I'm pretty sure it's like two peas in pod w/ the 6.5 C. But when I saw Whittaker's offer the T3X SS in 6.5C I wanted to get in on that deal and did.
I'm not sure what's the official definition of "Rifle Looney" but we spend hours splitting hairs and quoting "ballistic gak" on our favorites.
When you buy the 6.5C, welcome to the club (if you're not already a member in good standing).
