I used to shoot NFAA tournaments for years. We shoot those out to 80 yards. I've come to the opinion that a deer at beyond 30 yards is far less likely to drop, jump the string or whatever you want to call it. I've shot some at 40 and missed a couple at beyond 50. Both I had quickly said 45. Both were a quick decision in a hole that I hadn't ranged for and didn't have time to. Both were a bit further and the arrows fell low. One arrow had brisket fat and hair on one blade. I watched the deer bolt, stop, look around, walk some more and stop and stare back trying to figure out what the noise was. I finally watched him wander over the hill feeding. Imagine my surprise when I found tallow on one blade. Where he stood the first time there was a small glob of blood but no more. I had watched the arrow fall under him right behind the front leg. I mean it must have just shaved him. Your chances of a miss are probably better than a wound. I don't know about the rest of you but my left right is usually great, it's range estimation that screws us.
