Hello, So I am new to LR shooting and have figured out how to range estimate targets but once I have got the range I am not sure how much I should turn my elevation knob to reach that far out,also I think I grasp the concept of MOA if that helps. Do I need a balistic card or some sort of balistic application to be able to do this. Sorry if this has been asked before I tried searching but could not find anything. BTW I have a remington 700 sps tactical with swfa ss 10x42 scope mildots
