Good question. I know my shooting skills both on the range and out in the woods within any given yardage. For hunting I have set the limit at 30 yards and not beyond it. I know I can confidently place the area where it needs to go (within a small margin of error) out to that distance. Ofcourse, most of my shots are much shorter...under 15 yards actually but I know I can accurately shoot farther if needed.
