10 years from now, a lot of guys who've bought guns in proprietary cartridges will find that they have no source of readily available factory ammo and will HAVE to roll their own. (And not just for ARs.)

I think there's a big element of vanity involved - why else introduce ANOTHER 6.5mm round for the AR platform, when there's already one on the market? Why have similar - but non-interchangeable - new .30 mags (Winchester, Remington, and now Ruger) except so some corporate type can say "Look! We did it too!"
