I think the engineering part kicks in once the cannonball leaves the ring, or maybe around the mass of the shrunken ball. If the cannon ball retains it’s mass in it’s shrunken size does the gun have enough power to move it? If it does, then the gun is a ship cannon already, just a convenient size. If it doesn’t and can only shoot because the balls are as easy to fire as regular shot, then as soon as the ball exits the ring it is a cannonball being moved with the force of a small shot and likely drops to the ground an inch or so past the muzzle.
That’s my take on the cannonball as well. Being diminished reduces both its size and mass, so when restored it should have the momentum gunpowder gives a bullet. I’m guessing it might go a couple feet. But this is so interesting I’m gonna ask the player in my group who has a masters in physics how far she thinks it would go.
