If you pursue the RAR, just avoid the rotary mag.
In general I agree, but the two RARs in 6.5 Creedmoor I've owned have fed well from the rotary magazine.
Might also comment that I've seen a BUNCH of big game of various sizes taken with not only the 6.5 Creedmoor but the .260 Remington and 6.5x55--along with the 7mm-08 and 7x57. Have also been beside other hunters who used the same rounds, using various bullets. I have yet to be able to see any difference in "killing power" with any of them, and would even throw in the .270 Winchester. The two major differences I see in all those rounds are:
1) Recoil--which tends to be less in the 6.5s, though that also depends on the rifle's weight, and fit to the specific shooter.
2) Availability of factory ammunition or brass/bullets for handloaders. (Aside from all that, 6.5 Creedmoor factory ammo tends to be more accurate than any of the other cartridges mentioned.)
