Although this has been discussed in other NGSW threads, the telling part of this video is the line: "We see this more as an ammunition program than a weapon program." When this video came out last month, it confirmed that the reason the GD submission was a bullpup was that its cartridge ran at conventional pressures. The only way to get the velocity required by the Army was to use a long barrel.
A few years ago I saw a proposal to use a neckless polymer case to allow existing 7.62 NATO weapons to use sleeker, higher-BC bullets. Once you remove the neck of the case, the ogive can move farther back. That cartridge would have traded some muzzle velocity for speed and KE at long range, though.
