What target shooting do you have in mind, and just how serious are you about it? Their are several target games. Every thing from shooting candles out to shooting a Blue faced 20 yd. target to field target shooting to 3D to shooting to air targets. etc etc etc. Their are varying opinions above, and that is OK. Different strokes for different folks. Build a longer bow like your favorite shooting shorter hunting bow ,and pick a target game. Shoot against yourself with the 2 bows, and study the results. Then you will have answered your own question. For me it is heavier bow by at least a lb., lighter draw, a deep shelf, string nock, Low stretch string, bone tip over lays, and longer limbs for better string angle, and less string pinch ,and shooting 2 fingers under. If you find that longer, and heavier is not better for you cut the bow down ,and make it the way you want it. That is the nice part of bow building . You can do what you want with it.
