I recently shot my first bear with a bow. The first shot was quartering away slightly, it hit a little far back going in and hit lung on the way out, after a short distance with no blood trail to follow I was able to put another arrow in him this time through both lungs. He ran off again with no blood trail. I was able to watch him the whole time and I did recover him and upon skinning him found tons of fat, so I guess my question is has anyone else had problems with no blood trail on a fall bear? Should I use bigger broadheads? I'm using the g5 montec 100 gr heads (1 1/8 diameter hole I believe). Any thoughts or suggestions?
