[QUOTE="4xforfun, post: 879854, member: 9172"] I use two different techniques. But let me state up front that I do not travel far when I hunt, and here in ND things are relitivly flat. I make up a chart for my scope based on the forseen environmental perameters.. I know that the elevation is going to remain constant to within 200 feet and I look at the extended forcast to find an average temp. If it looks like there will be a wild swing in temps I will make up a new dial up and hold over chart....I do not mess with the wind chart. I plug all this into my Seirra I6 program and make up charts for the top of my scope. See pictures. I also have a kestral 3500 and the Shooter app. When I have time I use this most. I plug in station pressure, temp, azmith (ie 49th parallel), distance, and shooting direction and hit enter. It figures spin drift and coriolis. Absolutly AWSOME!! The top chart is 9/3oclock wind from 5 mph to 30 mph out to 1000 yards im MOA...I have an NP-R1 reticle. The second chart is dial ups using the forseen avarage environmental parameters from 350 to 1500 yards in 25 yard incruments. The bottom is my holdovers (using 22 power) on my NSX NP R1 reticle. Like I said, if there is time I go to the shooter...way more exact at extream ranges. ALSO, DROPS ARE COMFERMED ON PAPER TO EXTREAM RANGE OVER MANY DAYS TESTING. Not just "print and shoot"..... Good luck, Tod [/QUOTE]
