NOt familiar with the 190, but I presume it does not allow direct cleaning rod access through the chamber. You remain positive that the rifle is unloaded. No insult, just gotta say it.
Try a steel section of cleaning rod, like the M16 version, IF you can angle it into the bore from the chamber end. **Put the female threaded end towards the patch loop.** Drop & swing & repeat a dozen times. If no movement, or the rod won't go in, try a good length of bicycle brake cable sheathing (the plastic coated stuff) without the center cable and with something plastic to center itself in the hole of the impact end.
Cut to extend only 4-5 inches past the chamber, when against your cleaning loop.
Sleeve that in some sort of plastic, like small-diameter PVC pipe, etc., leaving about 3/4-inch of the cable sheath exposed.
Brace your sleeve in the chamber area somehow, so the sleeve sheath won't just bend past the chamber.
Apply hammer to end of cable sheath. It has a lot of air space, being a helix shape, and has some flex. Inspect plastic sheath at chamber mouth every few strikes, and increase hammer-whomps until the patch loop breaks free.
DO NOT "lube" with water or anything containing water. The cotton will expand and get stuck much worse. Try this first with nothing added. I'm not even sure adding Liquid Wrench is safe with cotton.
