the arrow isnt always an indication of a hit! i shoot a 9pt this yr hit him perfect. exited rite in his armpit. the arrow or broadhead had hardly any blood just a few hairs on the fletches. he ran 120yd and expired. i shot an old big bodied buck last yr while stalking. hit him in the shoulder and saw the arrow sticking out and it broke off when he took off. i compared it to my other arrows and it looked like i had 4inches of penetration but its hard to tell really. an arrow can and will back out as a deer turns to run. i searched off and on the whole wk. not much blood at all. shoulder hits happen. ive found myself aiming a tab bit further back and im pulling a lil over 70lbs.
