Our college gun-club has a .22 revolver. Its a S&W, but I'm blanking on the model number. I think its 61, but I may well be wrong.
Its a great gun, wonderful feel, good trigger, fun to shoot. Except it keyholes every shot. Its been back to the factory three times now, and it still keyholes. We had our first practice of the year about a month ago, so the club president says to me "Hey Andrew, mind seeing if the revolver is still keyholing?" So I did, not expecting much. I loaded it up, shot a full cylinder single action, loving every minute of it, because firing revolvers is just fun. When I emptied the gun and took a look through my scope to what the gun was doing, there was nothing there. I couldn't figure it out. After further inspection I found that it was shooting one target to the right. Not an inch, or a minute of anything, but a TARGET to the right, probably 14 inches at 50ft. There was a nice little 1.5" group in the black on that target. (all keyholed) Too bad it wasn't the one I was shooting at.
