Muzzleloader breech plug is plugged!

The only other option is to buy a new breech plug if you can find one locally.

I feel like that may damage the muzzleloader don’t you think?

Can't imagine that clump of goo being stronger than the steel breech plug around it. The breech plug handles charge after charge of explosive. Is it a 209 primer or a conventional cap?

I get clogged holes that are very tiny in carburetors.
I have soaked some of them and they do not clean out.
I break out the soda blaster.

You can put cooking baking soda in it and it will clean very well without removing precious parts.

Torch tip cleaners work very to clean out a tiny hole also coupled with the soda.
Soda blast and you will see the place where the hole is then work it over with tip cleaners.

Dawn soap and water is all I use to clean a muzzleloader.
You could possibly heat that plug end with a hair drier and have some non drying oil hands to soak into the dried crud.
PB blaster is the devil as it will dry. Use 3-1 or wd40 or LPS 2 or Rem oil
