I hate to tell anyone to remove the breach plug but it seems that doing so is about the only way that you are going to get the mystery stuff out of your bore. Use a pad of some kind on your vice jaws so you don't mess up your barrel. Pads can be any metal that is softer than steel. Sheet brass or aluminum is a good choice. When you tighten the jaws of the vice, do not tighten them as tightly as you can, just snug enough to hold the barrel and not allow it to twist. Do not clamp the vice over the breach plug or you can just cause it to be harder to remove. Use as large of a wrench as you have and used a piece of pipe over the end of the wrench as a "cheater bar" to give yourself as much leverage as you need to remove the breach plug. Use steady pressure on the wrench to unscrew the breach plug. If it just won't move, take the barrel out of the vice, plug all holes and fill the bore with a 50/50 mixture of automatic transmission fluid and acetone. Let it stand for a day or so to allow the mixture to penetrate the threads. Then give it anther try. If it still won't budge, put it in the vice and use a torch to heat the barrel around the breach area. Get it good and hot and then apply ice to the breach plug to chill the plug. Then immediately apply the wrench and unscrew the breach plug. The heat will expand the barrel and the ice will contract the breach plug making it easier to remove.
