Don't get me wrong, it is a neat cartridge, and I wouldn't mind building a rifle in a 6 Creedmoor or 6XC, twisted for 115s.

As a commercial cartridge.... it would have lots of looney appeal, but have my doubts on whether it would sell. I'm not exactly seeing 6.5 Creedmoors flying off the shelves around these parts, or many rifles built for it in general.
