Sound like you spent a lot of time looking.. Thats good you didnt give up to quick..
I differ on my thoughts than wmi and bruce and agree with buckshot on the shot placement. If there close up, 10 yds or closer. Wouldnt you shoot high?
Technically speaking if you shot correctly, bending at the waist etc, your shot would still be fine. But the way that most hunters adjust to shoot they end up shooting high at a close target out of a stand. Thats the way most of my hunting buddies miss. Some of them even aim low a couple inches to compensate for close shots.
