I really doubt cartridges would be lost or damaged, and once manufactured filling them should not be that much of a hassle.
That's the BBMG approach, with the power potential of a hybrind you can do more with less
Not that I'm saying that the way I propose is the only way to go about it, but it does seem like a more plausible way of achieving sustained fire.
Sustained (10 second bursts, that sort of thing) fire would be out of the question with homemade cartridges, if this is one of the design objectives then an on board fuel-air system is the way to go.
The problem in my opinion is what happens if the fuel that will have no doubt leaked into the pilot volume gets ignited. With piston hybrids, the "pilot area" has to be kept vented to atmosphere.
Also, that particular design runs the risk of sparking on the outside of the cartridge (uselessly, of course).
Details that can be worked on, as I proposed the projectile-seal approach is probably better.
for the number of shots typical for a full auto/semi auto gun cartridges + launcher will weight more than launcher + projectiles...
You have to factor in the weight of compressed air and fuel tanks which a cartridge launcher avoids.
