After I made my first post, I went out to my building shed, after it warmed up to zero. I found a similar wedge I had used a couple of years ago. The wedges was flat, but had four of those self stick rubber bumps you put on the bottom of stuff to keep it from scratching. two were about an fat inch apart at the wrist area, and two were about where the heal and toe are. Again this was taped to the stock to give you a flat to work with. Off subject Eric, I did get out to practice for the York today as it was calm, but needed snowshoes, and laid out on top of the shooting bench. It was a balmy ten degrees by two o'clock, and calm.
