Vern: Are you saying that JUST the two patches are lodged back by the touch hole? Or did your jag separate from your rod with the patches and now the patches AND the jag are lodged back by the touch hole?
If its only patches, buy a patch pulling jag. They come in two shapes, a single rod that looks like a cork screw for wine bottles, and a double wire version, that has two wire twisted around each other to provide two different points to grab the patches to pull them out. Check Track of the Wolf, or some other supplier closer to you. You will need to know the screw thread size for your rod when ordering, but that is about all, and tell them the caliber of your gun, but the tool is a handy thing to keep in your range box.
If it is the jag and the patches together, shooting it out is about all you can do, now.
You probably will have to remove-- and replace-- that touch hole liner, to get the powder behind the wads, from what you have described. Most liners are filed flush, and no longer have a screwslot in them to use to take them out. You will have to use an " Easy-out " screw( reverse threads) to take out the liner. IN the process, the liner is usually damaged, so that it must be replaced.
