 you'd put together your range sketch or your range fan cards. And that would tell you where you're 100, you're 200, you're 300, and you'd identify the areas of threat that you would be able to mitigate. And if there's multiple targets, you understand that your elevation and windage knob wouldn't have to be messed with, especially at 160 yards. You could literally just look quickly, glance, and know from the reference point whether it be a building, whether it be a lone tree, whether it be a parking lot, maybe it's a road.
