In my paper last night there was an article about a guy who found (?) a muzzle loader near a trash bin. He and his father were going to clean it and it had a stuck breech plug. So what did this fabulous duo do? They put it in a vise and took a torch to it and apparently the son was standing in front of the muzzle. The son is now dead. No further details were given
Good little tid-bit; lesson to everyone playing with muzzleloaders... make sure they don't have a charge set if you plan to take a torch to it!! Or really, as with all firearms, make sure they are safe and unloaded before working on/handling.
I'd try penetriating lube down the barrel, if that fails, pull it from the stock and hit it with a torch. Just don't be like the two idiots in the above quote!
OR... you could take it to a gunsmith and let them figure it out.
