[QUOTE="Dave King, post: 9558, member: 3"] JBM Thanks, I really appreciate that. At first glance it appears that that my Thumb-Rule info is off by 4 to 6 inches (on the short side) at 1000 yards depending on the position (near or far) of my situational wind. I'd not considered creating a Scientific Wild *** Guess (SWAG) factor to account for the increased Time Of Flight (TOF) at distance and how to increase my wind induced deflection numbers. I'll work on that! I did find it interesting about the angular change continuing to increase after the projectile exited the wind effect area. Appears to be about a factor of 2 as does the 500 to 600 yard deflection as compared to my original Thumb-Rule stuff. Is this "point mass" calculation/program available in a form that I could use? I'm a little short on higher education skills and am primarily a "poke and hope" type with geometry. [/QUOTE]
