Home Forums Hunting & Shooting Ask The Gunwriters New Army cartridge announced to replace the 5.56 in service rifles and SAWs

I just read an announcement that the Army would be adopting a high velocity 6.8 Cartridge for the new service rifle and squad automatic weapon.

Does anybody know anything about it? Is this just a lead free light weight bullet out of the existing 6.8 SPC in polymer case ammo?
