I think I managed to copy most of Emerics info, I hope this works:

The 1980 declaration of the Federal Republic of Germany, made after the NSMATCC evaluation, summarize this position:

 

The NSMATCC evaluation weighted the 5.56 mm cartridge so heavily (because of its low weight and volume) that the 7.62mm cartridge was at disadvantage before the tests even started.

 

However, the results of the shooting test have proven without doubt the superiority of the cal. 7.62mm and thus reinforce the FRG position that two calibres will be required: for the infantry rifleman as small as possible within effective terminal ballistics limits and light machine gun in 7.62mm calibre.

 

In consequence, the only logical result is to take advantage of the G11 4.7mm caseless technology which reduces volume of the cartridge in comparison to 5.56mm by over one third and reduces weight by about one half. At the same time, the 4.7mm caseless ammunition, during side by side test with the SS109, shows equal test results as that

recommended for the SS109.

Thus, the final decision would be to complete development and produce the G11 to have it ready for mass production in 1985, for

eventual introduction into the FRG Armed Forces starting in 1987, continue with a light machinegun in calibre 7.62mm developing a caseless machinegun in that same calibre for MG / light machinegun utilization.”

Yes it does. Thank you!

As you can bet, with this kind of official annoucement, Germany was not going to adopt the SS-109 until all the nails were put in the G11 coffin.

I think that's a good example of the difference between the US's view and the German's view on this topic.

The US wanted a "universal cartridge" for the squad, and the SS-109 was considered sufficient to deal with ligtly armored targets up to around 550 m.

For Germany, the 5.56 mm was not able to cover all the roles of the LMG, so 2 rounds were needed, and the 5.56 mm was "overpowered" for only "protecting the LMG".

Thanks for sharing that info. Definitely a different perspective. 

Its a shame they didnt take a closer look at the Austrians, who also used the MG3, and then protected it with 5.56 AUGs.  Cold War 1984 goes hot, Austria really had the best mix of anyone - MG3's, AUGs, and Glock 17's. 

In terms of a less "overpowered" caliber, it would have been interesting had they pursued the 4.6x36 /HK36 more. Work on reducing bolt impact to improve FA contolability, bump capacity to 36-42 (something divisible by 3 for 3rd burst) and equip it with an optic. Could have been a low recoil, lightweight, 1200rpm 3rd burst launcher.

Micro-calibers are very prone to the water in the bore problem, and the smaller the bore, the more serious is that problem

They also are very ineffective against improvised cover, such as walls, earth/sand berms etc

They did, but in a caseless form... the G11 was the "product improved" version of the HK36, with an even lighter round, a "less strange" magazine (still impractical because it was too long), and better full-auto stability.

If you want to revive the "micro caliber fever" of the 70s, you could reload a .17 WSM with a scaled-down "balle D", you will end with a 29 gr bullet with a C7 around 0.16 at a MV around 750 m/s.

Yes, its just it didn't work ;-) Of all the downsides to the G11, that ACR report is pretty damning - not only did it not improve hit probability at any distance, but it was markedly worse then a M16 with iron sights. 

Is there any indication of why both Germany and the US were so gung-ho on hyperburst? Had it worked well with test fixtures, and just not translated once put into the ACR trial with real guns?

Thats good to know. But the Germans did seem satisfied with the risk with the 4.73 for the G11, and I havent heard reports of the 4.6 MP7 having water logged bores? But perhaps thats because they've been deployed to the desert.

Design was sound and the prototypes worked awesome. SAS was delighted with them

However, these were the years in which political management destroyed both CETME and Santa Barbara facilities. They calculated costs so badly that they have to cut corners like crazy. Both CETME L and AMELI were so poorly built because of such "savings" that had to be discarded just after some years.

We have heard a lot of terror stories of soldiers who had to go to missions with non-functional rifles, or with rifles that they knew that were going to fail after a couple of magazines. Talking about the magazines, they were specially crappy, the same than plastic furnitures...

Indeed nowadays CETME-L built by american companies work reliably. The problem was not the design at all. The same happened with the batchs for our Guardia Civil, of much better quality

what a sad and shameful end of our capabilites. And nobody went to jail because of that

In NGSW news, we may have a finalist picked in the coming months or so, with contracts expected to be issued by April. Its also alleged that the current geopolitical tensions may hasten the rifles adoption.

The article also seems to re-confirm that the competition is now between SIG and TV for the 6.8, with Textron no longer mentioned.

Thanks a lot for the fix.
