In matchlocks and flintlocks, there’s an open hole at the chamber area where pressure is released. It’s somewhat similar to a pressure nozzle in a rocket, but the rocket doesn’t weight as much as a firearm which allows it to move more easily, generally speaking. So my question is, does the pressure leakage lead to any measurable movement in a sidelock firearm?

If a muzzleloaded cannon would have the touch hole placed at the bottom of the rear instead of the top, so that the touch hole is pointed towards the ground, would that cause the cannon to fly up into the air?
