[QUOTE="LaHunter, post: 857197, member: 54963"] Can someone that knows explain to me how angle cosine works for shooting angles. What is the math involved. I know there are range finders out there that do the math for you, but I can't spend that kind of money. I have a Leica 1600 that will tell me the sight angle. [U]EXAMPLE[/U]: I am shooting a 'raw' distance of 430 yards at an angle of 35 degrees. The cosine of 35 degrees is .819 (I have a calculator that knows this). Do I multiply 430 yards by .819 to get a 'shoot to' distance of 352 yards? Thanks for educating me on this. I am heading to Big Horns in WY in late October and hopefully I may get to use this info.
