A lot of the earlier Archaeologist mistook the short bow for a child's bow. It was not very powerful. It was probably around the 35-40 range. It didn't have to be very powerful. Just powerful enough to sink into a buffaloe's lungs. They would ride up close enough to shoot the buffaloe's lungs full of arrows, and then go shoot another one, and in short order, the buffaloe would colapse, and there is dinner, hides,glue, tools, etc.
