Hiked up on top of ridge and heard 2 cow calls.  Stopped and listened for a min and had this bull come out from the timber and start working the treeline towards me.  Go ahead of him and climbed on a stump and nocked an arrow.  Ranged the gap at 70 and when he hit it I cow called and stopped him in his tracks.  Arrow found its mark and he went 5-6 yards and it was over.
