Dump the CM and go 308. Creedmore over rated, marketing hype BS. My 6.5 SWEEDMORE will do everything the creedmore will do, and then some.
If it's marketing hype it sure has stuck around for quite a while, quite a while actually.
I have no need for one because I have something on either side of 6.5 that works but if I didn't have a 6mm or 7-08 the Creedmoor would for sure be on my very short list.
