[QUOTE="Dave King, post: 58591, member: 3"] Matt27 No problem. Let me explain better too... to try to eliminate confusion when talking to other shooters. A mil (milliradian) is a unit of measure, it can't change based on the scope power setting. Your scope is calibrated (I assume) at 32x so that the subtend distance between 2 marks on the reticle correspond to 1 mil. As soon as you change the power setting you can no longer refer to the distance subtended between 2 marks as 1 mil (it mearly becomes "marks" on a reticle)...it becomes some other mil value. By changing the power to 16x we will assume that the distance subtended between 2 marks is 2 mils. You'll need to verify this with a calibrated/striped pole to be exact. In a perfect world if your scope could change power to 8x you'd have 4 mils between "marks". So, at 16 power when your round struck .5 "of a mark" low and 1 "mark" to the side it was 1 mil low and 2 mil to the side. 1 mil is ~3.44 MOA as you note. I believe if you think of it in this manner you may find it quicker to make the come-up ands windage correction(s). [/QUOTE]
