Okay, so as mentioned at;

"Another innovation is a new automated ammo storage/loader, located in a turret bustle. It is separated from crew compartment by an armored bulkhead which greatly increases crew survivability."
A 'bustle' is "a framework worn at the back below the waist for giving fullness to a woman's skirt." So that would be the extra section add-on at the back end of the turret.
I suppose then that perhaps the armored bulkhead has maybe a sideways roller with insets for the rounds to fall into, and hull integrity is maintained even during a fast rate of rotation as they drop into the slots in the bustle and are somehow loaded through into the turret and into the gun breech after the roller rotates 180 degrees. How it does this without the old way of having the barrel "...lock at +3 degrees..." for loading, must be quite a trick, especially given the "Rate of fire: 10-12? rounds/min".
Or maybe it uses a reciprocating piston that pops through the bustle 'baffle armor' into the turret, rather like a giant-size version of a gas-powered self-loading machinegun.
Maybe the bustle has a separate internal bulkhead that separates the ram from the magazine, through which a slotted roller rotates so that as it brings the round around and through, it maintains airtight integrity in the bustle, as it drops the round into the ram receiver and then drives it forward through into the turret.
Could be when the gun fires the recoil slams it back and as it reaches the end of the throwback, it drops out the old shell firing pin or whatever and drops in a new shell, then as it recoils forward on springs, it self-rams and relocks automatically, doing this somehow regardless of firing angle.
That is not a lot of time for cycling out of exhaust gasses from the barrel before breaking open the breech into the interior of the turret chamber, unless the turret chamber has positive ventilation. But it would take an uncomfortable level of interior positive pressure to do that, so maybe the entire internal recoil-reload mechanism is enclosed in a thin metal pressure clamshell casing, not a bad idea anyways to keep crew from getting tangled up in it. With a taller clamshell casing, the barrel could be at any angle inside the clamshell and still do all that.
Thus if the bustle is hit, the internal bustle roller prevents penetration into the ram, keeping the turret safe. This is speculation of course.
With all that, there might not be much room for climbing back and forth from side to side inside the turret.
Jamming. Hmm. Increased crew endurance, flexiblity and utility and so on. Yes, there is that. You can't just give it a kick or a whack with a handy weskett wrench, can you?
And now, I will check out the Swedish Stridsvagn 103.
Thank you gentlemen and God bless.
