Blockage from nipple area to the main Barrel
I have a Traditions Fox River fifty black powder. i have cleaned the gun and removed the nipple and have tried to send a wire through the whole that allows the fire from the cap to go into the barrel but the wire refuses to go into the barrel for me to see it when i shine a light down the barrel. the screw on the side would be the best way to get into that area but the screw refuses to budge, and i was wondering what you would use to free that screw. I know from working on antique engines that pb blaster and wd-40 works to free bolts that are rusted but i do not know what to use to get the screw free. Any information about how to get the screw free or what to use to get the screw free would be of big help. thank you for your time and advice.
