I disagree that if you hunt long enough,you'll lose a deer.While anyone can make a poor shot,many deer will recover.I strongly feel that any solidly hit deer,including gut-shot deer should be recovered.I get called to track alot of wounded deer because I'm on a list of people used to track deer for a controlled hunt.The absolute number one reason the vast majority of deer are not recovered is because people push them way way too fast.I've recovered several gut shot deer this year alone.50% of the time,the deer were still alive inthe morning and 100% of the time they were within 50 yards of where the hunter last saw the deer.
