Its nothing new, its been around for decades...
Sure, it's been around for decades, but I am pretty sure there isn't a Army or USMC conventional unit that has ever drawn polymer-cased ammunition from the ASP for a qualification or live-fire range.

Let's see, a 5.56 case weighs about 93 grains.
So 100 rounds, the cases weigh 9,300 grains. Or 1.33 pounds.
So cut the weight of the cases by 50%, you save 2/3 pound.
A thousand rounds, you save 6.6 pounds.
7.62 and 50 cal will be much bigger gains.

They do some research on this every several years.
Sometimes the design is a radical departure such as the Dardick tround:
https://en.wikipedia.org/wiki/Dardick_tround
or the telescoping casing discussed in the OP linked article.
while other times it is a same chamber different material design.
I am watching this with interest since it seems material developments are making it closer to being practical.

They're looking at 7.62x51 first. They believe that the technology has improved to the point where it may be viable now...time and testing will tell.

Related to this, if we can get a cheap and widely available 6.8mm round out of this research and development effort, that would be awesome.
Sig Sauer's entry is about halfway down the page here and is most similar to the M4.

For civy use as a hunting/long range carbine target round?
Because what they are looking at isn’t an intermediate cartridge. It’s a 7.62 replacement with better armor penetration and range. Recoils would be slightly higher.
Not something to replace the M4 (mil won’t take the hit on ammo capacity and the extra recoil is going to result in much worse accuracy and lower rates of fire)

You're correct that the polymer cased rounds are for 7.62 replacement, but I'm also saying that 6.8mm is being looked at for 5.56 replacement in certain cases as part of this same research project. Sig's entry is a hybrid steel+bass case in 6.8mm.
I’d rather see them use salmon.

At least nobody would microwave those rounds accidentally. If you were my coworkers you would probably still put fish in the microwave on purpose.
Isn't this what the AS-007 was designed to use out of the box?
Army has been using polymer (or some other consumable material) cases in the M1A tank since the 80s.

Sure, I think it is also being looked at as a SAW replacement. That might make sense.
