willing to bet it was a high backbone hit...above the spine. though that sounds REALLY high it isnt as high as you may think. the spine is pretty low on a deer above the vitals. i hit one there this year when he ducked the string...3 inches of penetration with a 3blade muzzy. 60lbs of KE...20yd shot. good red muscle blood for a long ways...dried up....GIANT hardcore manhunt with me and 5 buddys..walked a good 1/2 mile 5yds apart not leaving any leaf unturned..hes still alive. definently sounds like thats what you hit.....that or possibly the shoulder.
