Blockage between cap nipple and bore.

That is a pretty good breech plug tool set up you have. I use my heavy bench vise to clamp the barrel in pads and forge a wrench to fit the breech plug. When clamping the barrel make sure it is clear of the threaded area the plug screws into.

That breech plug tool should do the job, @Taevers .

It’s just plain old table scraps with a couple of mill cuts to fit a barrel. The trick to “getter out” projects is a push, pull with the Billings wrenches or large tap handles.

Do not do the above, it's a stupid idea and dangerous.

Yep, some idiot may have dumped 100 gr. of Bullseye down the barrel!

When one does clamp the barrel in a vise, be sure the jaws of the clamp are not compressing the barrel where there may be threads in the breech plug you are trying to remove.

Also be sure there is nothing that may impede the removal of the breech plug such as the drum in a CVA/Traditions breech or a touch hole liner that is threaded into the breech plug.

I would plug the nipple and then pour boiling water into the barrel, being careful not to burn yourself. It may take several attempts to loosen up the remaining grease. It looks like the grease is still holding some of the lead. The barrel will get very hot. during this procedure.
Remove the plug from the nipple, get some cleaning patches and a cleaning jag. You should hear and maybe see some moisture and air come out of the nipple.
CAUTION, dry patches will get stuck. Use two patches for drying the barrel. Then lubricate a patch with oil to avoid the possibility of getting the patch stuck. Last thing you need is having the cleaning rod stuck in the barrel.

I poured about 7 litres of boiling water down the barrel yesterday. Let it run out the nipple hole. Got some black stuff out. Blew air through nipple hole and shot another chunk of patch/wad out the barrel. Still no movement of the shot. I'm going to make a steel rod with chisel tip such as Grenadier1758 suggested and try to get the shot knocked loose. If that doesn't work...breech plug removal.
