Was wondering if anyone could help me out with some dimensions for a traditional Cost Style Box Call. If I've read correctly I believe that the call starts out from roughly a 2" square block and that the sides are cut at 5 degrees but once the block is cut about how wide should the top and bottom of the call blank be? While I'm at it I may as well ask how long the box should be 7 1/4" or 7 1/2"? Any help would be appreciated.
