Re: Precision Shooting 1Part 2: Optics, Data and Logic
Very weldone Ward, that is a great Post indeed Sir,
Theres a couple of things that I would like to know? One was the Wind Chart made for a differant rifle than the .308 as used in the Math Example
And 2, Why on the wind chart where it said use half values and the full value was IE: 4.5 the half value about it was stated as 2.0 and not 2.250 meaning 8 clicks instead of 9 because at a 1000yards that will be off 2.5" and the only reason I ask this is because the software that I am using has the wind correction feature but if I do the Math on a .308 at 1000yds that would be 10x10 devided by 11= 9.0909090MOA, But when my program does it, IT comes out 8.5 which would then place my shot 5" off, so then I cheated and adjusted the figures by instead of deviding by 11, I devided it by 11.8 and then it was closer, As wth the 700yds that works out perfect but seeing as you use the same figure to devide the 800yds I think this might be more of an issue for the very Long Range Shooters, But not for Hunters who keep the distance down to under 500yds,
When I did the Math on 1000yds with a 20mph wind like the one on the chart my software said the L to R was 17.0 MOA but again when I did the Math it came out at 18.18 which will put me off by 11.8 inches, So what would be the correct thing to do in this situation ???? maybe change the 17.0 to 17.6 as a Rough halfway point between the Two, I dont know,
Ward, again thanks for A Terrific Post
John
