Okay, okay my good friends - I got the message not to leave Bore Butter and patch down the breech! I have learned a lesson - okay? Please keep in mind that I haven't shot a match in over a year and a half. That's very unusual for me, but I got interested in other things.
I sprayed a liberal amount of "Deep Creep" down the barrel first day and let sit for almost a week. I don't think anything got past the jag, although I was able to clear out the vent to an extent. At least I can push a pick all the way to the other side of the bore, so that tells me there must be a little space between the jag and the plug. I then took some leather strips and sandwiched them between a vice and the barrel, tightened as tight as possible. Took a large adjustable wrench and snugged up to the breech plug then wacked it with my forging hammer - no go! It just rotated in the vice! I tried this at least two times and then decided to let it rest.
MY plan is to now spray the Deep Creep in the flash hole and stop it up with a tooth pick or something - maybe some tape of some sort. I'll let it sit for another 4 or 5 days and try it over again. I think I need to find a better way to grip the barrel besides using the leather. The jaws on my vice have a bit to be desired being they are a little narrow. I am leaning towards Eric Krewson's methods. I don't think it's impossible to remove the plug, I just ain't doing it right. I'm not sure what my Oxyacetylene torch will do, but I'm thinking this will help also. Thanks again for all your help guys. I will keep you informed.
