I'd have to agree with Ernie Bishop here.
For 7mm-08, i agree not going over 150gr of bullet weight. With the longer(heavier) bullets, they protrude too much into the powder space.
Any of his mentioned calibers would more than suffice, although i would add the 284 Win.
If i were to get a gun, specifically for shooting long range in 6mm (243), it wouldn't be the CM. I'd stay with 243Win, or have custom built around the 6XC, designed by David Tubbs a known long distance champion.
