Hello, I do not speak English so I use translator.
I think it's best to use the click turret, why? that if one angle shoots measures written in the turret will not work.
To use the click calibrated in a straight line use parallax wheel, as the photo attached, the green area corresponds to the area where you do not need exit Zero adjusted. next to each distance necessary will click to hit the kill zone by distance.
I apologize if you do not understand, but I use translator
