If it were mine, I'd get me a piece of brass rod, and carefully slide it up against the patch and/or patch holder that broke if it is still stuck in the bore, and gently tap it out from the breech end of the gun with a small hammer or block of wood. The brass is soft and should not hurt the bore at all. I have used this method more than once myself with 100% good results. :wink:
The other methods also sound good to try also. This is just a way to do it if you have it stuck pretty good. :grin:
