That don't sound good. Twice this weekend I shot two deer higher than I wanted to, both dropped immediately. One got up 8 min later and ran like her rear was on fire. Never recovered a single deer that's done that in my life. None I've shot and none for others either. The other one I had to kill a few minutes later with a pocket knife. Always watch a deer that drops like it's going to get back up. If it even starts send another one.
