I know that Tony is not wedded to the notion of forcing the new cartridge to be compatible with the M16/M4 family of rifles...Actually, now that I think of it, there's a very good reason that he should not be trying to "sell" the armed forces on a 5.56-compatible round.
History (of the smokeless powder era, anyway) tells us that every time the military adopted a new cartridge, they also adopted a new rifle and machine gun to fire it.
But, (except back in the blackpowder days) they have never adopted a new cartridge for the purpose of converting and upgrading old weapons.
Looked at from that perspective, cartridges developed for conversion of existing 5.56mm weapons -- such as 6.5 Grendel and 6.8 SPC -- have virtually no chance of being adopted.
