One thing that struck me as a potential weight saver are pencil barrels. But of course you can't dump massive amounts of ammo through them - they will melt eventually. They seem to keep their zero very well though. Modern heat treating seems to be a game changer.

My question is how much demand are we actually going to see for mmg's going forward?

Well that is a big question.
IMHO the MMG is becoming more important than it used to be. Or rather its importance is now acnoledged again. For several reasons.
Volume fire weapons on allmost any vehicle are more important nowadays. During the Cold war era pintle mounted MGs where allmost everywhere. But they mostly where intended for AA self defense... or a moral measure in case of air attack. Now a general self defense weapon that can be used in case on an ambush or sudden contact is important. The importance of the MMG increased with the proliferation of RWS.
Forward bases, observation posts etc need to be guarded and defended. A primary role for MMGs.
MMGs are the one heavy weapon that is seldom restricted by ROEs. It can be made available in large numbers and at allmost any tactical level.
MMGs provide a lot of fire power with few men. Which is important for armies with low manpower and nations with aging populations and low manpower reserves.

The MMG including long range and indirect fire came back in Afghanistan. Now in Ukraine we also see massive use of these.

       graylion said: Time to define what we mean by LMG

A LMG is a machine gun fired from bipod.

Personally I distinguish SAWs for LMG by using the former term for SCHV LMGs like the MG4 or the Minimi and the latter for full power rifle caliber MGs like the MG3,

The drawback to making up one's own personal definitions is that it typically causes confusion.

A "SAW" (Squad Automatic Weapon) can be a SCHV LMG; SCHV automatic rifle; full power, rifle caliber LMG; full power, rifle caliber MMG; or full power, rifle caliber automatic rifle.

And not all machine guns fired from a bipod are LMGs.  Below is a M240 MMG fired from bipod.

That's interesting.  I never heard of indirect fire with machine guns having been done in Afghanistan.  Got link?

I know at least one French captain that, having probably read too much reports from WWI, tried to do that with an AAN-F1, but the results were absolutely not satisfying. The ballistic of the 147 gr ball loading is closer to the Mle1906 .30-06 than to the 8 mm Mle1898D...

This is why I mentioned it. Just in case it might happen.

I tend to prefer technical descriptions. The role doctrinal ones usually change over time and are not the same anywhere else.

As far as I knwo the M240 is a GPMG and when its used from bipod its used in the LMG role and if its used from tripod its in the MMG role. MMG being defined by the use of a mount and being rifle caliber.
In German nomenclature there isn't a MMG. It its fired from mount its a HMG. If not its an LMG. But internationally HMG is used for non rifle caliber weapons fired from mount.

Could have been worse. He could have read some of the "three shots and then steel" stuff that was popular for a while back in the 19th century.

I come back to 8.5x63 ... ;)

as regards 12.7 SAPHEI. what about replacing with 30x113 as has been suggested? Them guns are pretty light.And there are gas powered ones available. So, if starting from nearly scratch, I'd go
 

  • 4.6x30
  • 6.8x51
  • 8.5x63
  • 30x113

Besides what EmericD wrote I have read somewhere some time ago that the Brits experimented with it.

I know that the experience in Afghanistan has resparked the interest in the German Army for the use of MG from mount. The need was there. Early on there where few mounts available and only a few people trained on their use. This changed and the mounts where used quite extensively.

IMHO it makes little sense to have 8,5 and 6,8. Both are intended for long range use.
A true intermediate makes more sense. This could be used for rifles and infantry MGs.
8.5 for al other (GP) MGs and possibly sniper and marksman rifles.

I am not a fan of the 30x113. I don't really see the use. If you want HE trowing in a ligthweight package 40 mm HV does that. 30x113 guns will allways be to large and heavy for dismounted use. 40 mm AGLs are far better for this purpose. Maybe design a more modern version with a more streamlined grenade of the same weight to reduce flight time and improve accuracy.
If its about penetration 30x113 isn't great as well. It also has no KE projectile. A 20x139 mm AC is the better choice for that.
