I bought a Peterson Christmas 2012 bent bulldog a few months ago. I have been having trouble with moisture in it. I first thought it was my technique, but I don't have any trouble with my other pipes. The other day I noticed that when I tried to put a pipe cleaner through it, it stopped dead in its tracks. I took the stem out, and looked inside the mortise where it meets the shank. They ended up drilling it wrong, and re drilled it, but didn't fill the crater that they left. It seemed pretty wet in there. Could that be my problem with moisture? If so is there a way to fill that?
