It seems to me that if the AMU was going to the effort and expense of creating a completely new cartridge, they'd have given it the correct case taper so it could be demonstrated in machine guns. That's what Cris Murray did with his 7x46 UIAC.

Some fairly knowledgeable individuals think that the proliferation of hard body armor will pose a threat in the relatively near future. If this is true, the ability to defeat such armor may call for a much higher velocity round -- and possibly of smaller caliber -- than the 6.5-7mm cartridges currently being proposed.
