In the recent press release for their NGSW entry, Mars, Inc. and Cobalt Kinetics claim to be launching a 140gr 6.8 bullet at 3,200fps from an 18” barrel.

It looks like they are using a traditional case though - basically just a fat WSSM style case.

Right off the bat it looks like a "fatty" double stack magazine based system, while they can work; that puts significant sidewall pressure on the magazines and also puts pressure on the spring/follower which in turn makes it harder to get reliable feed from the lips. Magazines will probably cost as much--and weigh as much loaded--as the rifle.
