Variables are constantly changing. Your etched turret is not. Dialing 8 minutes on a scope and dialing to your 400 yard mark takes the same number of clicks and time. One is adaptable, one is not. It’s a waste, and takes away from the adaptability of a scope. I guess you can think about it and count clicks to change off your etched turret if it’s different, but then why not just run a moa based turret and skip the brain game. I want to make the best shot I can at 4,5,600 yards. It’s too easy to mess a shot at that range up. I want as many variables I can control in my favor.
