[QUOTE="bigngreen, post: 646628, member: 13632"] I learned a little about air flow during this shoot that I had never really put together till going out this far. The shoot had us shooting through a saddle about mid way down range, I know this would compress the air and speed it up and the wind reading showed this and I usually add 50% to my wind value when in this kind of spot but when the bullet landed I was of by 4+MOA and had my buddy over correct which rarely happens, usually I under estimate. After he made a correction and was on target I was watching the mirage and I figured out what got me, we were shooting [B]over[/B] the compressed fast air, I could see the mirage accelerating at the saddle but higher up there was a distinct air flow that was slower but more stable, when we focused on the mirage in this upper air flow vs the lower our windage tightened up. We ended up having 62.5 moa up and 13.5 moa for a 17mph wind from 8 o'clock, I wish I could have picked up the trace as it would have been a doozie!!! [/QUOTE]
