[QUOTE="LRNut, post: 2244027, member: 3230"] I agree that early morning before the sun comes up there is no mirage, but quite often it is calm. But I honestly have not seen too many animals at long range before the sun comes up. Another difficult condition is the sun setting in your eyes - impossible to see mirage. Very cloudy days, forget it. On the other hand, if there is snow on the ground, it is almost always visible. Let's talk about danger space in the context of wind. A 14x14 target means you have 1/2 MOA allowable wind error either way, or 1 MOA total. A .338 300 Berger at 2850 drifts .7 MOA per one mile of wind, which means you must estimate that wind within 1.4 mph and not have it change at all in the TOF of 2 seconds - and that assumes your rifle shoots 0" groups at that range. Even a 1/4 minute rifle has an allowable wind error of .75 MOA, which means you must estimate it with 1 mph and not have it change in the two seconds of flight - and according to Litz's wind array experiment, the wind is never steady (just hold your Kestrel into the wind for two seconds and note how fast it changes). Not sure how that becomes becomes an expectation no matter how fast the wind is blowing or changing. At some point, it becomes too far. [/QUOTE]
