Now that I think about it, there is a quest in Skyrim where you help reopen the East Empire Company. Long story short, you assault this island and they use what is supposed to be cannon fire to destroy the island. It looks more like Alduin's fireball things but whatever.

It should be limited to cannons though. Let's just say the magic that binds Mundus together wouldn't allow an explosion in such a small metal area, like the barrel of a gun.
