I have made a couple dozen bows from walnut. 95 percent were were made from saplings big enough to get 1 3/4 inches off the fades and, 40 to 45 lb range. 62 inches long for my 25 inches of draw. Knot free wood. It will take set, with less than average cast,and it will belly fret, or any variable depending on the bow makers skills. I made some real dogs in the beginning. Once I learned the character of the wood I made some nice bows from it. Easy to work with, takes heat well, and takes more time, and work to turn out a good one. 2nd string wood like birch, but with enough time ,and work can make a nice bow. Both woods are soft hard woods ,so I can't speak for the durability of either wood as a long term hunting bow. Both woods dent easily.
