Well, I draw the line at putting a scope on a flinter Buck Hunter(see Sabotloader, I do have my limits). My Great Plains flinterhas a hooked breech so I just take the barrel off, remove the touch hole liner, and stick the breech down in a bucket of water to pump it. Of course, as Cayugad mentioned, that's not so easy if the barrel is pinned. I don't see why you couldn't do the same thing by replacing the touch hole liner with a Zerk fitting if you can get one with the same thread.

Something I've never gotten around to, but always wanted to try,is setting up a 36" x 3/8" aluminum tube with a hose connection at one end and some kind of brush set up on the other end so that you could brush the bore with water running out of the brush end of the tube. The trick is attaching the brush is such a manner that the water can still run out of the end of the tube. Right now I'm refinishing the Zouave stock. Maybe the "flushing rod"will be thenext project after that.
