I'm 20 foot up he's 15 yards away. He's quartered to a some. I hit hit high in the pocket, not high. High in the pocket
Quartering-on will frequently result in a single lung, plus liver and gut. I shot an anterless deer a couple weeks ago quatering-on that bisected her entire body and shattered the off side rear leg. She almost went off her feet at impact, did a cartwheel about 40 yards off and I thought she was done. Amazingly, she made it another 125 yards after that. Blood was decent coming from only the high impact spot as the exit was plugged. If you hit where you believe, it should be a dead deer and I would suggest giving it a bit of time and then getting some tracking help....as that also gives you dragging assistance.
This is exactly what happened to me last year right before dark. Arrow went in behind her front left shoulder and came out her right hindquarter. Doe did a cartwheel, ran head on into a tree and ran a few hundred yards into neighboring woods. I started tracking half hour later with virtually no blood but I had seen where she went. I hear crashing around so I backed out and came back 2 hours later. She lay about 50 feet from where I backed out. Must have been other deer. Good luck.
When they stop and walk away one of two things happen. First and hopefully the deer stops and drops dead. No brainer there. But more likely when they stop and walk away it's a shot that is behind the diaphragm.... so in that case you better give it six plus hours before even thinking of tracking. And when I say tracking I mean any and all tracking. Don't even walk 50 yards on the track. Doing so your likely to bump the deer. Climb down quietly, back out away from the direction the deer went even if that means walking way out of your way. Then come back later and start the track and assessment.
