Advanced Marksmanship windage calculations for 300wm 190smk

[TheChad-->]

Ive done some research on windage calculations based on the ballistic data I got from the computer at gseven.com. are my calculation correct?

wind deflection for 10 mph wind at 9oclock (mil/mil scope)
200- zero
300-.5
400-.7
500-.9
600-1.1
700-1.3
800-1.6
900-1.8
1000-2.1

so I divide each windage calc by 10 to get a decimal number that can multiplied by the wind speed to get an actual mil compensation. Then I can take that number and multiply it by a decimal number that correlates to the wind direction( 90deg- full value, 65deg- .9, 45deg-.75, 30deg-.5, 15deg- .25 ) This looks logical to me...thanks for any input!!

Ballistic FTE says:
100m - 0.0 mils
200m - 0.2
300m - 0.4
400m - 0.7
500m - 1.0
600m - 1.2
700m - 1.6
800m - 1.9
900m - 2.3
1000m - 2.7

Definitely quite a bit different than what you are showing.

You can zero elevation at whatever distance you like but I recommend zeroing windage at 100 meters as by 200m a 10mph wind will definitely have affected your zero.

I am using gseven.com and on my iphone i have Bullet flight by Adanced Arament.
at 1000 with BF I get 7.6mil drop and with gseven I get 7.7mil drop. And windage deflection i get 1.9mil with BF and 2.1 with gseven. not getting 2.7! i have a 1:10 26" barrel and use 190smk at 2950. Thanks
