That is intentional, actually. The Abrams heavy bustle offsets the weight of the armor and gun keeping the turret well balanced despite it's huge size.

Why waste weight on a bulkhead when you could balance it just as easily with better rear armor?

Admittedly I don't understand why the weight of the bulkhead is an issue in the first place.

Be that as it may a blast-proof bulkhead is a pretty handy protective element to have. Chobham on the back on the tank only helps in the rare instance where the turret is hit from behind. The bulkhead protects the crew in the event of any penetration of the bustle. It is very hard to justify extra armor if that armor comes at the expense of such a vital protective element.

[Novorden]

Make the bustle longer. Make the rounds longer and thinner. Triple stack them in the bustle with a tray autoloader.

Problems = Solved.

Then you can fill the hull with fuel tanks for #winning.

Edit: I am too lazy too measure but those 125mm shells look oversized.

Everything is rounded up to the closest cm.

[The Kievan People]

As I thought, your propellant charges are huge. Like Xbox. They almost twice the volume of a NATO 120mm charge.

A 120mm NATO cartridge is about 980mm long and 160mm across. The combustible section is about 54cm long.

Here are some eastern rounds for comparison as well: http://www.pof.gov.pk/products.php

Here's an idea:

What if tank guns were a bit like revolvers? Where instead of the loader simply loading one and firing, he loads the drum. Couldn't that mean that it could fire fast without the time it takes to load one?

Just an idea I had awhile back.

1. Tank gun rounds are huge and heavy. This would make for a hugely heavy and unwieldy drum that would limit your elevation, depression and general handling of the gun.
2. Tank gun rounds are huge and heavy. Loading one is hard work. Loading a drum would be flat out humanly impossible even if the whole crew pitched in.

Just use a regular autoloader.

Sounds like a weird type of auto loader.
It wouldn't save much time between shots, and you would certainly increase time to load the drums. Plus the drums/drum system would take up more space, which is not something you want to do.

You have two options to implement this:

1. Attach the revolver to the gun itself. As others have said, this would add a good deal of weight to the gun itself, altering its balance and significantly increasing the swept volume inside the tank and/or your tank's overall length with the gun forward. It would also reduce elevation and depression, as mentioned by others.

2. Mount the revolver to the hull and have the gun return to a specific position after firing so the revolver can load it. This is how normal autoloaders work, so there's no advantage but you do have the significant disadvantage of needing space for both the revolver and a human loader.

Thus, neither option brings any useful advantages.

Modern automatic loaders already do this. Typically the gunner or tank commander hefts the shells into the machine when it runs out of rounds.

What's the steepest incline a typical MBT could safely drive up?

I think he meant that the entire drum would be replaced with a new one when empty. Not manually replenished.

How would the loader lift this?

Is he secretly a 5 tonne cranekin?

M829A3 weighs 22.3 kg. Just four rounds will probably weigh more than the loader himself.

Cranekin should be celebrated, not forced to live in secret

I'm not 100% sure what you're getting at here, but what you're describing seems to correspond to an automatic loader - as far as automatic loaders are concerned, revolver-drum type loader arrangements have been outdated for some time now. Dual revolver drums that could be replenished from behind the turret is actually what the AMX-13 used (6 rounds each), but technology has moved on since then and it's far more space efficient to opt for belt autoloaders instead.




At top is the AMX-13's revolver drum autoloader, at bottom, the Type 90's belt autoloader - as you can see, the configuration at bottom allows for, ceteris paribus, a greater amount of ready ammunition.

As the FASTDRAW program showed, there're merits to having a separated ready ammunition configuration for which drums are somewhat more suitable (redundancy in the case of a hit to the bustle compartment) - but even then, there're more space efficient ways to store ammunition than revolver drums - as, yet again, the FASTDRAW program proved:

Sadly cranekin tend to get crushed by objects with masses at least two orders of magnitude greater than their own, reducing overall productivity of the work force.

[Yukonastan]

Or you could place the two carousels on the turret floor, with the rounds pointing up, and a relatively light grabber assembly takes the rounds off of the carousels, then deposits them in the gun at elevation.

As I thought, your propellant charges are huge. Like Xbox. They almost twice the volume of a NATO 120mm charge.

A 120mm NATO cartridge is about 980mm long and 160mm across. The combustible section is about 54cm long.

There, take your pansy round.

Hey, at least I didn't start with this one.
