That cartridge isn't even remotely like 6mm ARC, which is fatter than 5.56 and has a much shorter case.
Quite true. Since the drawing was posted with no other information, I can only speculate on the discrepancies.
-- Perhaps it was meant to be a "perfected" 6mm cartridge, giving 6 ARC performance in 5.56 NATO-size round?
-- Or maybe it is simply mislabeled, and was meant to show his take on 5.56 Neckless in TV-style polymer case?
...as near as I can tell, the 5.56mm bullet is 47 pixels wide, while the "6mm" bullet is 51 pixels.
51/47*5.56 is slightly more than 6.03
Thanks for that info. I was unable to measure any difference on the screen.

That would be my guess; and a pretty neat cartridge if it worked out.
TV is releasing their 6.8 cartridge to the civilian market:
Who will win in NGSW? What do you guys think?
True Velocity and global weapon manufacturer Beretta USA announced on Wednesday a strategic partnership in support of potential weapon production stemming from the U.S. Army’s Next Generation Squad Weapon program.
In addition to supporting True Velocity in weapon production for NGSW, Beretta USA will also take a leading role in the development of a variant of the RM277 intended for sale to international allies of the United States, as well as a semi-automatic variant of the RM277 rifle intended for civilian sale in the U.S. commercial market. Beretta Defense Technologies (BDT), the alliance of Beretta group companies focused on serving global military and law enforcement customers, will also explore other applications and chamberings of the 6.8TVC commercial cartridge in its extensive firearm portfolio.
SAAMI board of directors to accept the new cartridge and publish its specifications.
The 6.8TVC is a composite-cased round offering significant weight reduction, improved accuracy, and extended range versus comparable brass-cased cartridges. True Velocity introduced the 6.8TVC cartridge for SAAMI certification at a maximum average pressure of 65,000 psi with a 135-grain bullet at a velocity of 3,000 feet per second. It is the first composite-cased cartridge to be accepted for SAAMI certification.
...a strategic partnership in support of potential weapon production...
That sounds rather iffy.
From a friend at SHOT:
BTW They're getting a full 3350 objective in the rifle version while still retaining backwards compatibility with m240.
Weight is down to 3.5 kg with can for the r version too.
Perhaps I'm misreading the situation, but the fact that SIG and TV are announcing sale of their NGSW guns and ammo on the civilian market before the winner of the NGSW competition is announced, says to me that both SIG and TV expect to lose.
"Currently being considered for adoption by the US Army" makes a much better sales pitch than "Rejected by the US Army."
