[QUOTE="bullseyebry, post: 867033, member: 41295"] I did not have a P.D.A. With me and was carrying a sporter rifle which I expected to shoot on steep but not extreme angles as well as shorter distances. So basically the question was two part: 1. Determination of correct distance to target and method. 2. Application of that determination to a non-moa dial. This appears to be an issue because if you notice the ad's on LRH , you will see one for a "Gunworks" dial/turret , which has both yardage as well as moa marks. (I posted an article that was on LRH, which would better help understanding my question.) You see the premise of the article was that application of the cosine should be applied to the drop/moa and not to the distance ranged example: 400 yards ranged - 60 Deg. angle - MOA =4.5 Corrected MOA = (4.5x.5) =2.25 So you would dial up 2.25 MOA, which CANNOT be done on a yardage only dial. Using the yardage method it would be 400 X .5= 200 yards which you can do on a yardage dial. My gun is zeroed at 200 so I would not move my dial and just take the shot. I just ran these numbers on a ballistic program and it says I need to dial up 3.3 MOA! :) All while the target is moving away! [/QUOTE]
