I may of hit some of the gut, the arrow hit hard and didn't passthru. I am taking a guess at how much penetration I got. I know the arrow was definately sticking out towards the rear of the deer while he ran off. Puzzled by the fact that not even a trace of blood or hair. Wonder if he could survive the hit? What could I of hit to not allow the arrow to penetrate and stick out so far? Sucks, I won't be able to track him well since we have a storm moving in overnight.... Not sure what to do...
