How to Shoot Beyond Belief

[Ridge Runner]

also the part john burns doesn't tell you is that the BDC he uses is after the range gets to 700 yds and beyond is good for 1 set of conditions. change bar pressure, or altitude and it starts getting more and more inaccurate as far as your scope settings go.
To give you an example a 4" change in the bar pressure will change the POI of my 7mm AM 200" at 1500 yds, now granted you may not shoot that far but say a 4" change in bar pressure along with a 40% increase in humidity, and 2,000 ft elevation change and you miss the proverbial broadside of the barn at 900 yds.
