I shot a bolt at a deer with my xbow today. There were 3 deer in the area. All 3 took off on the shot. The one I shot at ran about 50 yards. Stopped. Looked back. Then walked out of downhill out of site. The other 2 ran a few hundred yards before stopping. I went to check blood about 20 minutes after the shot and couldn’t find any or the arrow.
Searched about 100 yards in the direction the deer went then backed out after searching for 20 minutes.
Do you think I missed? It’s weird it stopped running and walked out of site when the others kept running.
Your description sounds like a paunch shot deer. I made the same mistake in my early on my bowhunting journey. When you shoot a deer in the paunch, depending on the angle, you may or may not get a pass-thru. Often, the deer's reaction to the shot will be to hump up it's back, but not always. It will run a short distance and then stop. Sometimes it will go back to feeding, but usually it will walk off slowly, go into cover, and lay down. The worst thing you can do is to go look for the deer too quickly. The correct procedure is to sit for 20 minutes. If you can see the arrow with your binoculars, then go only as far as the arrow. It will smell like paunch and confirm the bad shot. If you can't see it, don't even go to the arrow. You want to back out avoiding the area the deer ran. You do not want to spook or disturb the deer. Wait at least 4 hours, then return to look for the deer.
When paunch shot, the deer will not feel good and will usually lay down withing 100 yards of the impact site. If undisturbed, it will die there. If it is spooked, it will get up and try to evade the danger and lay down and die someplace else. The first time it laid down, debris and paunch will clog any entry or exit wounds. All bleeding will likely be internal. There will likely be no blood trail to follow, and your chances of finding the deer are slim. That is why we don't pursue the deer for 4 hours.
You didn't provide enough information to be sure this is a paunch shot deer, but it is likely. Things like shot distance, angle, entry point all come into play. I had a similar situation happen a few days ago. Here is what happened to me.
I shot a doe that was quartering away. She was 30 yards which is about the longest shot I would take with archery equipment (despite the hype the crossbow companies put out, too much can go wrong beyond 30 yards). Between the time my brain said "squeeze" and the arrow arrived, she took part of a step. It was enough that the entry point was in the paunch. She was in an open field and I was in an elevated stand. With a good shot, I would have had a nice low exit wound and a good blood trail. Instead, there was no arrow. She ran forward and then ran an arc into thick undergrowth. She was still running when she entered.
I was pretty happy with the angle as it looked like the arrow path would have gone through part of the chest cavity, but I was not 100% sure. There was no arrow to be seen. It was early enough when I shot here that I was confident the arrow was not in the field. I mentally marked the place she entered the undergrowth. I then walked across the field to her entry point and marked it. I then headed back to camp.
I changed out of my hunting clothes into my retrieval clothes (I only wear my hunting clothes to hunt for scent control). Because, I was pretty confident It was not a complete paunch shot and that the arrow path did enter the chest cavity, I did not wait the full 4 hours. After an hour, I headed back out. I search the field for the arrow and blood and found nothing. I then slowly entered the undergrowth and followed the trajectory I saw her enter on looking for blood. I don't nothing for about 30 yards. I then found one spot where they was blood and paunch particles. I slowly continued on that trajectory for another 50 yards looking for blood and found nothing. I decided to go back to the first blood and try again . I paralleled that trajectory about 15 yards off the line I had followed in. It was so thick, I almost tripped over her.
After dressing and skinning her I was able to do a post mortem and reconstruct what happened. I did get a pass-thru. The arrow entered through the paunch missing the liver but exiting through the chest and puncturing a lung. Because of her movement during impact, the exit wound was high in the chest, about the same height as the entry wound. That change in trajectory must have caused the arrow to sail across the field into the undergrowth which is why I did not find it. All of the blood was trapped in her chest cavity. When I first cut her to dress her, blood came pouring out. So, even with proper elevation in my stand, the arrow left the deer as if I shot it from the ground.
Strange things can happen when bowhunting. I learn from each harvest. Deer can survive a paunch shot if you don't hit the liver, but usually don't with larger diameter broadheads. If you hit the liver, it is usually a fatal shot, but it can take hours for the deer to die.
