I have a case of the following: 2&3/4" 12AP 31/4-11/4oz nickel 'American Pigeon' loads made in Italy by Fiocchi. Can I shoot these through my 1930 vintage Utica Sterlingworth? The gun is in excellent original condition. I hate to throw those shells away as they were dreadfully expensive to buy.
They are orange in color with pic of pigeon in flight on them. Is orange color a warning or are they made that way so empties can be located more easily?
