I have a self imposed limit of around 25 or 30 yards. It's a combination of equipment limitations and the fact that I don't judge yardage that well. If I know for a fact something is 30 yards away and it's not alert I would take the shot. If I am not sure or the deer is wary, I would most likely pass.

I shoot a short draw length bow with fairly low poundage. My speed and KE is not very impressive, so I try to limit my range with that in consideration.
