:lol: You said mounted.....
Seriously though... I'd just wait until you shoot a bird late season, thats fully feathered, big, bright and just not shot to heck. One you think you might have used the "golden BB" on is a good choice. Just take a nice Pintail, diver or any other bird that usually isn't the most common duck you can get and start there... heck you may wind up trying to get all the "Utah" ducks on your wall by the time its all said and done.
