Seems like another redundant round with no advantage over old stuff and that will be out of production in a few years. Anyone buying one had better stock up. That rebated rim means you can't make cases out of commonly available brass.
You could turn down the rims on a 6.8SPC or 30 Remington, if necessary. Would be a pain.
If it takes off in the AR platform, as the maximum one can squeeze out of it, then there will be plenty of brass around for a lifetime of shooting. If it doesn't tickle the fancy of the AR boys, then it will die a slow death.
