I'm not disagreeing, because knowing the range of your target is critical, especially with a stick and string. But......how many answers and comments are "politically correct" but not really as important as it seems?

Hang on, don't get excited...hear me out. When shooting a 3D target, PINPOINT accuracy is the name of the game. But a deer has, realistically, an 8" circle to hit that will kill the deer quickly and humanely. You just don't have to hit the "12 ring" to kill a deer efficiently.

Do I think about the range while at full draw? No, I have that determined before I get that far. I'll see the deer coming in, think ahead a little, when the deer gets "there" I'm going to shoot it, and that range is...........

I sight my hunting rig in @ 25 yards, and leave it. I am 1 1/2" high @ 20 yards, and 1 1/2" low @ 30 yards. If I miss the "12 ring" on a deer by 1 1/2"........who freakin cares? I've punched both lungs, dead deer quick. Does it matter that I guessed 27 yards and he was 23? No, because I hold my 25 yard pin right behind the shoulder. Little high or low just isn't going to matter. We can "what if" that scenario to death, but I can "what if" that same scenario when used w/ a rangefinder to death as well.
