well, it would certainly need a name mall ninjas can get behind, like everything else thats been made since 2005, like blackout, spectre, grendel, patriot combat cartridge, wolverine and so on
ive also considered cartridges capable of matching .308 trajectories but easily chambered in existing AR or AK rifles, perhaps a .277" 120 grain bullet with .400 ballistic coefficient to match the BC and velocity of 150 grain .308 but using less energy, less powder and chambered in a shorter platform and was considering doing it on 7.62x39 brass while maintaining the original taper so to remain compatible with x39 bolts and mags requiring just a barrel swap on an AK or other x39 rifle
