Looks like the bottom bullet is attached to the top one fixed in place by brass throat.. I don't what would happen if the 2nd bullet becomes misaligned. There would be a bang and I don't know if the bullet would go through or gets jammed in the barrel. There are cases of misfire where one round do not come out and the second round jams and the gun blows up. I do not see any advantage two bullets may have over a heavier bullet. Powder is reduced and mass of projectile doubled -->slow bullets.

I reload almost everything I shoot. Reload recipes matched to the gun is much more accurate than the off-the-shelf ammo at lower cost. Most of the reload data you see have >95% powder loading. There are many formulae where the powder load is >100% (the bullet actually crushes the powder) and so I do not think there is enough space, say at 90% load, to accommodate a second bullet and so tradeoff has to be made. Even small changes to the powder can impact the bullet trajectory, I normally load powders in increments of 0.2 grains (0.013 gram) and for a 5.56 round, there is a noticeable change in the point of impact at 100 yards. This would be very much magnified at longer range.
I am not sure if there are big differences in the energy density in the powder. The shape of the powder may impact packing fraction, but I do not think the energy content changes much (between different powders the mass loaded is only slightly different, but that is primary for accuracy consideration). For different rounds, other than the powder brand, primary powder selection criteria is the burn rate. The burn rate then impact the pressure. Most of the loads are not too far from the maximum spec pressure of the barrel (although there should be a lot of margin).
I'd think twice before shooting a double bullet round.
Thought you were talking about a squad weapon. In the case of HMG yes that would complicate things.
Dumb question but don't the CSLS7 use 9mm? I thought the PAP or military don't use 9mm.Snow Leopard Commando with CS/LS7 submachine guns.

Yes, it uses 9mm ammo, and PAP certainly fields firearms that use 9mm ammo.

PAP and the Police use 9mm ammo, it's the military that use 5.8mm.
Thus far the military has little interest in 9mm SMGs, however the police and PAP has the requirement to replace the Type 79 SMG, still commonly seen with the police.

PAP urban brick? I could see some use for it but it would have some potential failure factor to. Out side of brick structures in fall in highly wooded along transitional climates areas it might also work. However as a general urban they tend to defuse colors to almost arid scapes.

What happens if white brick, grey brick or painted brick is used? Or concrete/glass building.... Will stick out more than a sore thumb.
