Sure serial production will bring prices down but by how much? The 277 Fury load should not cost more than M80 but it's not going to perform better than M80 either, the super round is going to be reserved for combat so train with one ammo and combat with another, not smart. Justification for all this, defeating LVL 4 body armor at 500 meters, how often is the average joe going to need this capability?Plus that whole NATO interchangeability thing has proven quite useful, the money wasted on this boondoggle would have been much better spend on anti drone shotguns and defenses. You know someone should address that whole defeat body armor threat, so a lvl 4 plate is 10x12 inches or so, good to know that $12,000 day optic will allow joe to hit that at 500 meters instead of wasting that $21 bullet on hitting a arm, leg, stomach or head.

US Army allocates record budget for NGSW Next Generation Squad Weapons in 2025.

https://www.armyrecognition.com/news...eapons-in-2025

The detailed allocations within the NGSW project include $23.133 million for the acquisition of 1,772 units of the M250 Automatic Rifle (NGSW-AR), which is intended to replace the currently employed M249 Squad Automatic Weapon (SAW) within the Close Combat Force. Additionally, $91.447 million is set aside for the purchase of 18,019 units of the M7 Rifle (NGSW-R), aiming to supplant the M4A1 Carbine in the same operational capacity. The budget also includes a considerable sum of $252.712 million for the procurement of 20,045 units of the M157 Fire Control systems, which are expected to be integrated with the M7 Rifle and the M250 Automatic Rifle to enhance combat effectiveness.

I agree with most of what you’re saying, with 3 caveats:

1) .277 will outperform M80 by virtue of ballistic coefficient. Not by enough to matter at the engagement ranges and weapons relevant to M80. We’ve been launching roughly the same weight, velocity, and diameter bullet at enemies for 125yrs, and it’s still fine in its role. As would be a .6.8, but with extra steps. As a sidenote, the 6.5x55 has been around for 125yrs, too, and the 240 (well, FN MAG) has been chambered in it and was adopted by the Swedes, briefly. Given the same case and projectile design, pressure limit, and powder tech, it would further outperform the Furry at all distances with less or equal recoil.

2) I’m maximally skeptical of it penetrating level IV plates at 500 meters with non-tungsten ammo. Mildly skeptical of it doing that even with tungsten ammo. Screwing around with ballistic calculators, I anticipate a velocity under 2,000 fps at that distance, and around 1k fpe. Existing military plates are rated to handle more than that from .30AP, and have been for two or more decades. As you mentioned, though, that’s not really a huge capability anyway. And if it is, everyone will just supplement their plates with ones that meet Level IV or, I dunno, try not to get shot.

3) the project might result in very badass DMRs and MGs, logistics and cost aside. No portion of this project was needed for the DMR portion of my optimistic claim, though. See caveat #1.
