That is a fairly steep angle though...arrow could\'ve deflected down after hitting the ribs instead of exiting through the chest and missing the vitals. ARVelocity, it sounds like you hit your deer a little far back and is probably a gut shot. I have since then gone back to hunt and had a chance to study the situation more and think that I got some of that no mans land myself. Found my arrow with out a trace on it, but i have a blood trail. By using this method we have found numerous deer we had lost the trail of but picked it up again after some distance.That or you may have hit the deer too high and hit that no mans land above the vitals but below the spine. Need to cut a little bit more yardage on the next one. :(Russell, tough luck, I feel like something like that is bound to happen at some point if you bow hunt unfortunately. Even a well hit deer may not leave any blood for 50-60 yards of more especially if it is not a pass through.
Angles from tree stands and even the body position of the deer need to be considered.
Personally I use a fixed blade broadhead ( thunderhead 100). Sometimes a blood trail can be lost especially if the deer is booking it like crazy through the woods because only droplets can be seen at times depending on your arrow placement. I have found over the years that once a deer is hit and it heads in a direction is will almost always stick to that general direction even if it doubles back it will turn and continue in the direction it started.
Shot a 8pt 205lb deer this morning at 18 yards in the lungs and it only went 100 yards. Particularly in the lungs if there is no pass through think i may have had a lung or airway shot. It will normally stick to deer trails where it can move easily.
At 20 yards or less, he/she will likely not "jump" the string to make you miss high. Corina, your's is a relatively predictable situation and one that more hunters experience than would like to admit. Consider: If you hit one lung, there are at least four layers of membrain, skin, muscle, etc. If it was a clean pass, some of these layers will overlap each other and poetntially close off the entry hole and stop the bleeding if he lays down (which you want him to do).
Remember to bend at the waist so as to not lengthen your draw and make you miss high. The key is give him a couple hours before you begin to 'track', or in some cases, 'push' your deer.
Deer Seeing Lights How long can I wait to gut a deer? After you have established the direction the wounded deer went, they usually head for water, or low swampy areas. I heard a big whack, he jumped straight up into the air and took off like a shot.
