The 243 Ackley appears to edge out the Creed in drop and drift but the idea of better hunting bullets is a feather in the Creed's cap.
Don't get this part? Plenty of good 6mm bullets. Although I am going with a plain vanilla 243 it's because I had all the dies, bullets and brass already. If I were to bother going AI I would do a 6mm AI but only in a medium or long action.
If starting from scratch the 6.5 Creedmoor has a lot going for it. I would go with a wyatts or other slightly longer magazine for either. The slightly longer neck and better barrel life of the 6.5 would appeal as well. Shoot 85 to 107 grain bullets and they start to overlap each other.
But the CM has the option of bullets over 115 that the 6 doesn't.
