I think most of us have seen this video, but it deserves to be trotted out again

At that same event IIRC there was a high impulse weapon system that was a single shot 40x53 HV that they mentioned shot flat enough to essentially be POA/POI out to like 300 yards. The video I saw disappeared and I haven't been able to find it, I think it was FN's prototype.
Recoil looked brutal but it seemed to have worked
*edit* found a picture of it
Found a cleared one:
And a brief write up:A KICKIN' 40MM SYSTEM
The EX41 may be relevant; it used a 40mm grenade with a 150m/s velocity.
Thats 50% faster then the the 40x51 MV.
Just for history, the FN "High Impulse Weapon" is a spin-off of the Lacroix "Samourai Urban Weapon" launcher developped initially for the French Army.
The initial goal was to field a shoulder-fired weapon for urban combat that could launch a 1 kg warhead from the inside of a room with minimum signature (and no backblast).
A "hi-low" pressure system was used to propel the 1 kg / 76 mm warhead at a MV around 76 m/s, but the live (incendiary) round used a flammable liquid and the effects were not really spectacular.
These Chinese auto GL are all high velocity 40x53 for export. And we have seen these in action in Jemen and Iraq. But its 13kg unloaded, with the addition of Airburst kit weight grows 2.8kg further,
''This air-blast kit mainly includes OS23 simple fire control and muzzle fuze binding device. The weight of the kit is less than 2.8 kg, adopting a method of timing based on rotating number. The fire control calculates the number of rotations required for the grenade to fly above the target based on the results of laser ranging, and then binds it to the fuze. When the grenade flies to the bound number of rotations, it is located at the top of the target, and the fragment would hit the hidden target into a hornet’s nest.''
Airburst kit .
But even domestic 35mm version has quite a kick
PLA?? ??? ?? 11???????? China QLU-11 sniper grenade launcher - YouTube ...

Or just settle for 16 kg and go with the AGS 30?
I also remember long ago seeing a picture in a International defence Review of a 30x29B grenade launcher which was a salvaged AGS 17 barrel on a scaled up Ithaca shotgun made somewhere in central america. No one dared fire it but it looked rather like the China Lake Grenade launcher.
The Czech RAG-30 has been marketed for many years but I don't know if it's found any buyers.
Anyone has the chamber pressures for MV 40x46mm or is it 40x51mm?
