I would clean it with some soapy water and a pressure washer. I would then add something like Naval Jelly, let it sit maybe overnight; rinse with pressure washer again, and it didn't come out, add a quart of Coca Cola (it has Phosphoric acid, which will work on the rust), let it sit and try the pressure washer again.

A cannon worm was used to do the job back in the day. Civil war reenactors May be worth reaching out to.

Unless you are sure there is no powder behind the ball, this could be a risky job.

cool cannon

I 'haven't yet read through all the other responses, but before I forget my thoughts and have to rush off ... if you budged the cannon ball when it was air sealed - what about using some spray foam insulation to make it air tight again ?, and then repeat your budging efforts while letting it roll down towards ground. gravity is a great tool

I don't know, but I think super glue would make it worse - just my thought

going back now to read what others have suggested :) I have to keep editing as I get new ideas

does the cannon itself come apart in sections ? could you remove the "butt" end, and see the cannon ball from the back side ?

pour Coca Cola down the barrel to remove rust ???

If I missed this information, I apologize:
What's the composition of the barrel?
Was it a real battle cannon or is a replica?

Cannon worm is a good option.

Could heat it up some and see if that would free it up, gonna be there a long time with a weed burner though.

Another option may be filling the chamber with water then pressurizing the water, it wont blow past like water, also won't launch the ball if it does catch because water will not compress behind the ball and build pressure like air.

Is that a solid ball or is it filled with powder?

Looks like some kind of hole in the ball inside the bore posted by the OP. That's what made me ask what this really is.
