Sounds like a recovery to me Arrow probably hit opposite bone and will be found on his travel route. Good Luck and let us see a pic when you recover him

How about some info about him? 10, 12, 22 pts?

That hollow sound usually says broken gut sack or diaphraghm to me. Either way from the angle you describe, the deers reaction, and your excellent decision to back off its very likely hes down not far off. I have seen gut shot deer die within 150 yards more than once. Typically its just a matter of not bumping them and letting them lay down and lose energy. I know its hard to do but backing off ona questionable hit is a deal maker whereas going in and bumping is almost surely a deal breaker. Good luck in the morning.

He's wasn't a monster by any means. It happened so fast that once I saw his rack was out to his ears and had decent mass I focused on the shot, which may not have been a great one. I'm guessing he's around an eight pointer. I'm a little disappointed with myself though. I hope I find him. Rain is in the forcast. I'm actually in Upstate NY visiting my inlaws. this will hopefully be my first NY deer

Did you find your deer?

I'd be concerned about the white fur. Whitetails have white underbellies, but the older they get, the more the underside of their chest turns a darkish grey. I would think the white fur indicates a gut shot. However, I've gut shot a couple deer and I've never seen them "mule kick" the way you described unless hit in the vitals, but that doesn't mean they never would. Again, the no blood sign is a concern. Every deer I've ever shot left blood withing 10 yards if the arrow went through the body cavity somewhere. But with the angle you describe, I cant imagine you missed the liver unless your shot was very far back.

I think you did the right thing by backing off and not following up too quickly. I just noticed you posted this days ago, so perhaps I'm a bit late with advice, but I'd give him a half a day or so and check the main trails leading away from the place you shot him. If that fails, check the brush around water holes. Good luck.

I'm guessing that this didnt work out well for our poster.
