If you are pushing fouling into the flash channel, you are cleaning the gun wrong. Try it this way:
On the first run of a cleaning patch( Moistened, but not wet) down the barrel, STOP when the rod is 1 inch above the breech. Pull the crud out. Now, use a second patch, and run it down all the way to the breech. Only the small amount of crud/fouling in that final inch will transfer to the patch, and it will easily soak up that small amount.
Read the patches as they come out. If they are black and Greasy looking you have lots of condensation in the barrel along with the fouling. Use a Third Patch- dry- to dry the barrel all the way to the breech, or powder chamber, and read that patch when it comes out, too. Feel it. If there is lots of moisture on the patch, either flip it over and run it back down, or get a 4th (dry) patch and run it down to make sure its truly dry.
As long as you haven't pushed a dripping wet cleaning patch down the barrel, there should not be enough water in the flash channel to cause a misfire.
Most of the problems with misfires relate to technique, and not to any mechanical problem with the guns. Its just that most new shooters haven't a clue how to go about cleaning these guns right, and don't even know to ask. We have all been there, and done that before. So, just ask, and join the club. :thumbsup:
