According to the link below, the rifle can fire a 135gn hybrid match bullet at 3000fps muzzle velocity.
Using JBM ballistics calculator (Link below), the bullet is supersonic out to 1000 yards. Out of a 16inch barrel, that is awesome.
300 AAC or blackout cannot penetrate level 4 armor it lacks the energy even at the muzzle. Neither can any of the 5.56 black tip rounds. The whole reason to go up to a 6.8mm sized bullet is it carries the kinetic energy needed to 600 meters to penetrate level 4 armor. This is also why you need 80,000 psi if you want to use a shorter barreled rifle. As was pointed out this also has a gas piston not the crap self impingment. Finally the infantry gets a real battle rifle not the toy sized M4. Anyone who has ever lit off a M14 in full auto knows that rifle means business. This round trumps the 7.62x51 mm by a good bit it should be a stone cold man killer with the streamlined 6.8 mm and fast twist rate you can send sleek high BC bullets waaaaaaaayyyy out there the 6.5 creedmore stays supersonic to nearly a mile and this round adds 30% more bang that a creedmore. To bad at 80k psi you have to use steel cases which means no reloading. The military doesn’t care about reloading every round is a single use item always has been. Used military brass is never reloaded by the military they gather it up in training and sell it for scrap. The Russians and the Chinese have used steel cases exclusively for decades they don’t even bother to field brass cases ammo steel is cheaper.
