Anthony, the Richard King designed by Richard King stock is a good stock for silhouette but not legal for Hunter class, you may want to check the Nesika Bay or Brown Precision Silhouette stocks for Hunter, they are both excellent for that purpose, their basic differences is that the Nesika Bay has a flat forend bottom and the Brown Precision has a somewhat rounded one.
I also have a McMillan Master Silhouette stock and I am happy with it, the stock has a flat forend bottom so depending on how you grip the stock with your forward hand will determine if you are going to like it or not.
