It's not that hard to design a shell that can withstand the recoil when it's fired and then crack when it hits something, High Explosive Anti Tank springs to mind. Regardless I repeat: This is still in the experimental stage for a good reason.

Besides I want to save the truly bonkers designs for the third semester and onwards.

True, I'm sure once the plot moves along and gets more serious everyone will be going through 'upgrades'. Have you considered a Sabot tank round?

Fluoroantimonic acid is absolutely nuts.  It's so acidic that it will eat through hydrocarbons.  I don't think there is any way to weaponize it without simply laying waste to everything in its path, including the user.

Then, what is it contained in?
