US Military Developing New Designs for Hypervelocity Firearms

Why do you need higher velocities for CQC? Would it not make more sense to implement this in DMRs or standard rifles to increase ranged proficiency and decrease bullet drop? I would think that in small spaces like room clearing higher RoF is much more important than velocities. What exactly is their reasoning for using this for close quarters?

Calico. It was a drum mag that used a windlass and a spring to push the bullets into the breech. Vid related, link for timecode below:

I suppose they could do the same thing with a large box magazine, quad stacked casket, to get something like 120 rounds of ammo.
Casket magazines always had problems with springs, just looking at the spring contraption of a casket magazine gives me hives. I'd be interested in seeing how winding it externally would be used.
In G11 you had to wind the trigger? I don't remember.

Frankly if America DOESNT do anything to improve infantry forces, they're going to get laughed out of every conflict.
This. Also this is talking about testing loads for the AK, which are very high. Every 1000th rifle that comes out of Kalashnikov is fired with incrementally stronger test loads. It's possible that some freak of metallurgy had an AK survive (ie not explode) a test load of that pressure, even if it didn't cycle afterward.

And now I've remembered that there was already a quite advanced bullpup with a falling block(esque) action: en.wikipedia.org
That's not true, most militaries want a relatively RoF of around 600 for their submachine guns, because with a high RoF you just spray your whole magazine into the room with one pull of the trigger, and you'll be lucky if a few shots land on what you were aiming for. To illustrate how important it is, the Skorpion even has this funky czechnology to slow down the RoF.
The easiest solution is to just make a belt-fed weapon that has the whole feed system integrated into a replaceable unit, so you can reload life if it was a magazine-fed weapon: modernfirearms.net

I'll admit i am a tad curious to how well the tapered barrel would work.

The theory is solid, and it was invented for hunting rifles. It's basically the same as flechette ammunition, but without any of the downsides. I'd say these are the real questions:

i dont think barrels would be such an issue. i mean fuck they are planning on using it for smgs, right? they dont really need to be even rifled for that.
i guess easilly exchangable barrels would be ideal, but again, locking system would need to be robust as fuck at these velocities.
i am more curious how they plan on making an loading mechanism

I'm working on a squeeze bore barrel design that also uses progressive oval rifling.
the oval rifling doesn't tear up the jacket like progressive cut rifling can, and is easier to clean.
Barrels could be produced by hammer forging or ECM.
