Help
ok i need your guys help So ive been hunting late season hard so far ive been out evryday waiting for a decent buck. Well today it happened. a large main frame 10 steped out he was broken up but he had a double main beam on his left side. I first spotted him at about 150 yds out he was walking right at me he came to about 30 yds straight on and i was waiting for him to turn broadside. BUT, HE LOOKED RIGHT UP AT ME!!!! he stopped then he turned to the right and ran about 10- 15 yds. i pulled up the crossbow ( would have had my bow but my dad bought a new crossbow and was telling me how great it was and i try and shoot atleast one deer with every weapon we have.) so i had one smalll opening between 2 trees and i thought its now or never and i pulled the trigger. I instantly heard a loud smack and the deer took off on a hard run and i watched him run about 150 yds until he went out of sight. At first i thought i must have hit the tree because you cannot see the crossbow bolt fly. well anyhow i was bumed and decided to get out of the tree and look at where he was standing and sure enough i saw hair and the i looked found my arrow that had blood on it but couldnt tell how much because it went into the 6 in of snow. anyhow i followed his tracks for 30 yards and he was spraying blood like every 3 feet but it wasnt alot of blood but a decent amount and the blood really didnt look like lung blood but its hard to tell in the snow. also he bled instantly. The broad head is an over the top expandenable so i know the entrance hole is small Im going to give him 4 hours before i look i feel like i hit low i almost felt like i skimmed him but i heard a loud whack and i know i didnt hit any trees what are your guys thoughts where do you think i hit him and how long should i wait.
