Im gonna say torque as a well on this one. But never over look your equipment. Make sure your cams are not bet or twisting on the draw. Also check your peep if you use one, also make sure nothing has come lose on the bow such as sight and WB. Check everything over with a bow square, but at this point im going to lean more to a torque issue. You could also be drawing too much weight and torquing the be bow as well.
