[QUOTE="danacobb, post: 42499, member: 1696"] I'm definately no expert on the subject and haven't done much angle shooting in the real world but I have read quite a bit about the subject. I've read the difference between the angle cosine difference and some ballistics software is that the software takes into account for the time of flight. If you figure out your angle and take the cosine of it; that'll give you the distance that gravity has and effect on the bullet (ie. the horizontal distance). This does not however take into account that the bullet is still traveling the ranged distance to the target (actual distance). I know Exbal and the Sierra software take these factors into account. I would think a combination of the ACI to get your angle and then using the angle chart to get the scope adjustment would be the correct way. But like I said, I have no real world experience in this. Interested in your findings; keep us posted. [ 12-06-2004: Message edited by: Cobber ] [/QUOTE]
