The 6.5 Creedmoor is a fantastic caliber. I built one earlier this year,and it's a shooter.
The only negative to it is getting good brass,Hornady brass doesn't hold up too long before the primer pockets become enlarged.
I have a bunch of 22-250 brass that I'll be trying out as soon as I fire form it. Even though it takes another step prepping,if it will last twice as long as the Hornady brass it'll be worth it.
I also shoot a 260 Remington,and it's a great 6.5 caliber also,but the Creedmoor allows you to use you magazine even when loading the bullets out to the lands. The 260 will limit you to magazine length with the same bullets unless you want to turn your rifle into a single shot using rounds out near the lands.
The 6.5 CM/260 Rem/6.5x47 Lapua will all do the job for you,and don't forget about the old 6.5x55.
