I got Cabela's 1851 Confederate Navy .44 Caliber Revolver for Christmas and am having trouble getting it apart. The instruction manual says to push the wedge out and separate the barrel from the frame. Well, easier said than done. For the life of me I can't get the wedge out. I have no idea what I'm doing wrong, but I've already managed to put one nick in it and would really prefer not to do any more damage. Does anyone have this particular model and have some advice for how to get the wedge out?
