This is the time of year that T/C and probably other manufacturers get most of their calls about stuck breech plugs. Usually from lack of cleaning or over tightening.
Try using a hair dryer on the barrel. Heat it up long enough and you may get a little metal expansion to loosen the breech plug.
Should also mention that when done shooting at the range. Remove breech plug. That residue from powders like 777 turns to tar and will make removing breech plug difficult.
