Why exactly is bustle ammo storage not an option for type100? Not necessarily all ammo/propellant, but at least part of it?
Dimensions wise, Type100 is as tall as type99, if not a few cm taller. it's almost as tall as m1's. Turret length is approximately the same as type99 and just a bit shorter than m1's.
Armored part of the turret, the core turret is narrower, true. But again, type 100 has smaller caliber rounds and not necessarily all of them in the bustle - so why couldn't those fit?
Let us remember, there are two crewmembers in type 99's turret. There are 3 in leopard2 or abrams.
But in type 100 pretty much all the internal turret space can go towards the gun, the autoloader and at least some of the ammo/propellant. When i overlay m1a1 internal schematic over type100, i get almost the same internal turret length.
Basically, if type 100 doesn't store anything in the back third of its turret - then what is that room for? There's a whole bunch of space back there. There are actually two hinges on top of the turret, that seem to hold the back of the turret, as if it was a lid, opening the back side up. If so, that might be a logical position to take out empty ammo mags and insert new ammo mags.
