Epoxy bedding leaked into action screw hole...need advice!

Thanks for all of the advice and ideas! I plan on working on it this weekend probably. Our deer season ends the 1st and I am trying to make the most of the last few days in the woods.
Smart man, not something you want to do when rushed. You might take some of the epoxy and glue a nut and allen head bolt together and see if you can loosen it with the heat method. Kind of a trial run to see how much heat you might need.
 
The crappy part is...the allen head is stripped so my plan is to use a dremel to cut a slot in it for a flat head screwdriver. I dont really see another choice outside of trying an easy out.
Slotting is fine...if you have a MIG/TIG you can also weld onto the head of the screw to give you something for more purchase if needed.
