[QUOTE="Bravo 4, post: 1633832, member: 8873"] I only read but a few pages of this thread and seen a lot of guys speculating temp, baro/altitude, humidity, etc can change poi by 1 moa @ 100 yards. I do not think this is possible at that range. I went into my Ballistics AE app and, with a 0 yard zero (straight out the muzzle) and zero sight height, changed the conditions pretty severely and you probably cannot get 1/10” poi change of drop at that distance (more like 1/100”), let alone 1”. If you think that a 20 or so feet per second change in velocity will change the poi by 1” @ 100 yards then we long range shooters have been kidding ourselves all these years, there is no way my rifle should be shooting under 2” groups at 800 yards unless the velocity spread is practically zero.
