[QUOTE="BrentM, post: 877399, member: 61747"] Wind (not just left to right but 3d) I shoot mountain terrain. Absolute Barometric Pressure Temp Coriolus spin drift Humidity, to lesser extent. ** Wind. I adjust for elevation depending on wind direction relative to twist of rifling. L to R wind I adjust UP, R to L wind I adjust down. It is not much but at 1500 I have seen impact go low or high .5 MOA. 5-10 mph full value. I have not taken the longer shoots in heavier wind 15-20. Not sure if you consider that environmental or not, but I do. Same as thermal activity in the mountains. Air moves and up and down with the terrain and depending on if I hug the mountain side or shoot over it, depends on what happens to my bullet. [/QUOTE]
