LMGs are getting lighter anyway ...
So what about 8.5x63 for MMG with recoil moderating mechanism?

Most reports I've seen have the MG3 set to a more sedate 850-900rpm (for example, Austrias MG3.)
Was that the case in Germany, or did they retain the higher RPM bolts?

No, not even close. Tony's GPC was significantly smaller and much lighter than 7.62 NATO.
_____ 5.56 NATO ________ 6.5 GREN ___________ 6.5 GPC ____________ 7.62 NATO _______________
6.8x51 SIG is the same size -- and nearly as heavy -- as 7.62x51 NATO.

I think that a 80,000psi 6.5 Grendel or 6mm ARC (using Sig Hybrid tech) would be closer to Tony's GPC.
From what I recall, the 8.5mm machine gun just does not add enough capability to worth the trouble. The bullet is to0 small to carry enough HE for anti-material roles, so it can't really replace the 50 BMG.

They are MG 74 and different to the MG 3

No, its the lighter bolt. The Bundeswehr MG 3 cycles at 1200 rpm.

Not really. The ones that are significantly lighter usually compromise capability, become flimsy or are made from (very) expensive materials.
graylion said:So what about 8.5x63 for MMG with recoil moderating mechanism?
For an MMG the recoil absorbtion can be put into the mount. If one is required since the mount absorbs the recoil and vibration. If it is properly designed.

Like the FN Evolys?

Awesome. Are they still in production?

How often does .50 HE get used?

Despite various tests in WW2, the US never did adopt a .50 HE bullet. However, the current "business load" seems to be the MK 211, a version of the Nammo multipurpose (SAPHEI).
