[QUOTE="Longshot38, post: 240877, member: 11627"] The easiest way to do what you are talking about is to stop thinking in terms of inches and start thinking in terms of MOA. MOA or Minute-of-Angle is a unit of measure that is relative to distance. In other words 1 MOA is equal to 1.047 inches (just round to 1 inch) at 100 yards. Thus if your scopes turrets are set at 1/4 inch click then it will move you POI 1/4 inch at 100 yards (or 1/4 MOA) Now that you get the concept of MOA we go back the idea of MOA being relative to distance. In other words @ 100 yards a MOA is equal to 1 inch, @ 200 yards it is equal to 2 inches , @ 300 it is equal to 3 inches, etc...... An you also know that you scope moves your POI 1/4 moa per click. With these values it becomes easy to figure out how far you are moving you POI for a given range. You just multiply the number of MOA you move you POA by your MOA value for your given range. So if you have to move you POI 16 clicks (4 moa right) for 300 yards then you would have changed your POI 12 inches (4 moa times 3 inches). See that easy. [/QUOTE]
