Do you use an Angle Cosine Indicator (ACI) for uphill/downhill shots?

[QUOTE="Pons, post: 554995, member: 32348"] That method takes the horizontal component of the distance and using that for range ("rifleman" method). It could be useful in some scenarios. You could do the same thing with the Angle/Cosine indicator if you multiplied the cos of the angle against the distance ranged to target. Some nice things about the a/c indicator, you don't need a very steep background that is nearly the same horizontal distance from you as the horizontal component of the distance of your target to you. You could multiply the cos of the angle by your moa adjustment for the direct range (see link to article below) to get a hold estimation. Finally, you could enter the angle into a good ballistics program and get a more precise model of what adjustment is needed to get on target. see - [url]http://www.longrangehunting.com/articles/angle-shooting.php[/url] You could run some simulations using angles and the three different methods, then see what you get. Is your method getting you "close enough" to be "on target"? After all, isn't that the goal of much of this? Hope that helps Triple BB Here is an article with some diagrams and better explanation.
