the 6.5 creedmoor was yet another brainchild of the hornady corporation (new for 2007), expressly designed for target shooting (hence the name)... I have yet to see a box of cartridges in the shop, or a rifle chambered for it for that matter. My guess is that it is still a little new to be considered an equivalent comparison to the venerable old 6.5-08. As i understand it the 6.5 creedmoor was designed to utilze the heaviest bullets possible for the bore size, while still meeting magazine length requirements, while i really dont think it was intended for the AR platform, it seems, as the design has proved in the past, that the AR will allow a chambering of just about any practical cartridge application with the proper modifications and or accessories. I personally have high hopes for the cartridge, and based on what little i have read about the cartridge, i believe it has the potential to become a favorite.
I stand corrected! it seems upon further research, and a quick phone call to a good friend that the 6.5 creedmoor was intended for any .308 win. length rifle action. please check out this link below.
