[QUOTE="Broz, post: 795754, member: 7503"] That is the easiest thing to assume, but lets look at it this way. These are my own opinions and what works for me most of the time:). First problem would be getting this info that was solid, and not a changing wind. But we will go with what you proposed. Remember, the first wind started the bullet off path, (turned the steeling wheel a bit if you will). By 500 yards the bullet is now .9 moa off track or roughly 4.5" left from the 3:00 wind. The bullet will continue on this path with an final impact left of 2.1 moa or close to 22" at 1000 yards because of[B] it's heading that started at the rifle[/B]. Imagine the line of sight to the target and the bullet path being a "V". So the opposite wind that starts at 500 has a less effect because it has a much bigger job to do. It has to correct the bullet path back, and the first wind already has a 500 yard head start at this point. The second wind will do some correcting, and in result lessen some of the effect of the first wind, but in my estimation the bullet would still impact left from the path the bullet took from the first 3:00 wind. So can you see where the second wind would have to be a stronger wind to correct the bullet that was started off path from a 1000 yard angle? That is the key, when the bullet starts off path its error from point of aim increases with yardage. So, the second wind has a bigger job to do, and less time and distance to do it. Hope this made sense?? PS: I left spin drift clear out of my solution. Jeff [/QUOTE]
