Hey guys, calm down. He can have a 300 IBO if he is pulling 42#. IBO has nothing to do with draw weight. It is the speed of the arrow with a bow set at 70#, 30" draw, while shooting a 350 grain arrow.
but i wanna comment on ur bow set up..pullin 42#'s eh?..ur not gettin no 300 ibo not even if u were pullin 60
He would have an IBO of 300 fps if he was pulling 20 pounds or 200 pounds. Draw weight has nothing to do with IBO, excluding the fact that IBO is attainedusing abow with a70 pound draw weight.
