i shot a buck this evening and at the shot he ducked a little, i hit, i think, just under the spine/high lung, he took off on a dead run and the arrow buried up to the vanes, it was about 6-7 inches below the back line right behind the shoulder there was no blood trail but bright blood on the broken arrow. think its a lung hit? i think it is b/c he was on a dead sprint and never stopped and just crashed through everything. we backed out 4 the nite. i was using a martin cheetah 65 lbs, easton epics and g5 montec broadheads, it was a 30 yard shot. we tracked for about 125 yards b4 backing out
