Shaped projectile - Okay?
Crystal-encased lead - That's an interesting assumption. Crystal-encased lead is pretty much a revision of its own, since it seems like you want to make a hybrid material.
Crystal Casing - The crystalworks doesn't make dispellable-crystal. We'd have to summon crystal casing (and we take a while to summon crystal, by the way) on each shell before it's fired.
Your design is quite frankly just overengineering. You're trying to introduce a new material as well as forcing our magicians to spend massive amounts of time summoning crystal casing onto each shell. You're making an AP shell way too hard in both terms of the actual designing part and in its effectiveness.
Also, you're doing stuff like adding magegems and circuits to your shell. This is extremely overcomplicated.

Aerodynamic shells - Just because we changed their shape once doesn't mean we're at the pinnacle of aerodynamics.
Adding crystal - See below. And we aren't stupid. We can examine evidence. Are there bits of the shell scattered about the impact site? Wow, it must have shattered during impact! Is the shell somewhere else? Wow, it must have ricocheted!
Improved Speed - When calculating kinetic energy, velocity is squared but mass is not. Velocity matters much more than mass. Of course, improving speed and mass is the best option, but that's not particularly viable. This is modification of the shell, not a modification of the cannon.
Reducing impact site - No, not really. We can improve aerodynamics and reduce the impact site.
Manufacturing - I really shouldn't even bother with this. "We don't have much experience with doing the thing this revision is meant to introduce!"
I was going to edit this into my last post, but now I'll put it here.
Possible design that we could use the Research Credit for:
Future Design: AS-HAC-2The AS-HAC-2 is a
true autocannon.
The first change is an even smaller caliber size. [Variants of the AP Shell should be made for this size]. The new caliber is barely big enough to be called a "shell" at this point, but is still very sizeable. Despite this change in caliber, the AS-HAC-2 is still bigger than the AS-HAC-1 due to its additions. It can still be carried by one person, but generally we recommend two people for any prolonged carrying of the cannon.
We revisit the HC2, which is normally banned from ever being mentioned in the Academy, in this design. Its steam recycler component provides a very nice starting point and experience here. We use our extensive experience in everything steam and mechanics-related in order to get this one component into a state fit for the AS-HAC-2. We've had so much more experience with frost spells (including in the barrel of the AS-HAC-1, the cheaper frost towers, and more) too, that combined with the fact that most of the groundwork has already been done, this should be
very easy to do.
The steam recycler utilizes frost spells to recycle steam into water before it leaves the barrel without compromising the projectile velocity. This means we don't have to constantly add new water. Not having to add in new water every reload should greatly increase our reload times! That, and the AS-HAC-2 won't be dependent on nearby bodies of water anymore!
While if we just scaled down the AS-HAC-1's caliber, we could make it notably smaller, the AS-HAC-2 uses the space and weight gained by scaling down the caliber in order to implement an innovative new system: Self-loading.
The decreased caliber makes the ammo storable in crystal boxes. These ammunition boxes - magazines - are designed to be attached to a part of the AS-HAC-2 where normally the breech-loader would be. Before the recovered steam goes through the steam recycler, it moves past a mechanical switch that toggles the loading mechanism, inserting a new shell from the magazine without human interaction.
The result is amazing - the cannon can fire without a human reloading! It
reloads itself! The operator merely needs to attach a new magazine occasionally, and rarely refill it with water.
We're also making some tweaks to the cannon to allow for it to generally pressurize and fire faster. This is a smaller priority and isn't the major, but as this is now the major bottleneck in firing times, improving it is better. We've developed "heat" circuitry to keep the water at a higher "base" temperature, increasing the power of the cannon and the time to pressurize. Which is already very low.
The AS-HAC-2 maintains the swivel mount and crosshair. However, the crosshair has been improved to incorporate very basic predicted ballistic trajectories in it, allowing for the operator to easily estimate where to aim to hit different targets. It also maintains the same mount and firing angles as its predecessor.
The AS-HAC-2 should be an impressive weapon. Equipped with AP shells, it should be devastating. Their airships may be able to survive individual rounds from an AS-HAC-2, but with the sheer rate of fire from an AS-HAC-2 should easily bring their airships down. Against carpets, it's not even a contest - we can fill the sky with
lead our rounds; we barely even have to aim. Against infantry, the AS-HAC-2 is awe-inspiring. Its fire rate allows it to effectively annihilate huge groups of infantry all by itself.
TL;DR: A self-loading semi-automatic cannon with a smaller caliber, that uses a fixed version of the steam recycler we tried in the HC2.
Smaller CaliberWe're
starting to blur the line between bullets and shells here. The idea is to free up space for the self-loading parts, and to allow for easy ammunition storage to actually let the self-loading aspect work.
Steam RecyclerShould be very easy because we already tried it with the HC2 and have had a ton of experience with frost/steam stuff since then.
The Steam Recycler practically removes the need to add in water in reloads, making the AS-HAC-2 much faster to reload, and making it not rely on nearby water sources/the Restless.
Self-LoadingThis is quite difficult, but is the main focus of the design and shouldn't be
too hard. We have plenty of experience with steam and now have breech-loading, so this is most certainly not possible. We won't be getting any bonuses for this, but I'm somewhat sure we shouldn't be getting any penalties.
The self-loading aspect allows the AS-HAC-2 to fire at an insane rate. It's not automatic, but is semi-automatic due to the need for the operator/apprentice to cast the PSF.
Heat CircuitsThis is a minor and low-priority part of the design, but it should be easy because we have plenty of experience with frost circuits, and plenty of experience with heat. Fireballs. Steam engines. And whatnot.
Heat Circuits mean that the cannon should pressurize faster and that the same spell (PSF) should result in more power. Heat Circuits don't need external power, but also don't turn the water into steam by itself. It just keeps the water's "base" temperature notably higher.
ExpenseThe AS-HAC-1 is Expensive, and we have the Crystalworks. National Effort is impossible, Very Expensive is unlikely (but possible), Expensive is likely and the goal, and Cheap is unlikely.
The AS-HAC-2 does not obsolete the AS-HAC-1, as the AS-HAC-1 has larger-enough calibers that it can be useful in different situations, even with an AS-HAC-2 firing AP shells.
[Note to self: Include Magegems if we ever revise them to be better.]
Also,
Evicted, is the AS-HAC-1 being put on Crystalclads? Considering the weight and expense, it should be a yes, right?
