If we follow that - 24 rounds of grenades vs 210 of 5.56? not buying. no way can you replace the rifle with it.

You may be right.  It just seems like 30 rounds (4 + 1 x 6-rd mags) of 40mm HEAB might be a lot more effective, with higher hit probability, than 210 rounds (6 + 1 x 30-rd mags) of 5.56mm bullets in most infantry combat scenarios.

That is a really intresting question. But it would propably require extensive testing and analysis.

The potential at least ist there concidering that 210 rds 5,56 are ineffective. The last numbers I saw a rifleman barely can carry enough ammo to statistically achieve one kill.

Fully agree.  It should be thoroughly tested and analyzed.

and no suppressive fire?

If you want the ability to provide suppressive fire, why would you use rifles?

I do really love the idea of rifle grenades, on paper anyway they are definitely efficient pound for pound (and probably dollar for dollar-------little fuzed shells are pricey, and any kind of timed airburst thingy will be crazy expensive).  I think 40mm grenades are ~50% fuze by both mass and volume.  While obviously easier to hit with if you've got it, even a high velocity 30mm cannon won't punch through the kind of armor a good HEAT rifle grenade will.  Massed frag grenades, or the ability to put up a wall of smoke at a distance without calling anyone...... very attractive. 

My only potential beef/question on rifle grenades: can you actually get most troops to actually use them?  Is there a way to mitigate the recoil?  Or is everyone just a wimp but France, Japan, and some plucky Balkanites?  My impression is that while RGs are vastly more efficient in terms of payload delivered, most militaries have gone the 30-40mm tube route because rifle grenades are just so unpleasant to shoot. 

25mm OCSW round had both range an ability to penetrate armor  , Rifle granades have punch but are hard to aim at any real distance

It looks like the system you are showing is a crew served weapon.

Wouldn't a better comparison be to the 25 mm individual weapons ?

same ammo IIRC
