[QUOTE="User4302021, post: 1985885, member: 105322"] If you apply the cosine to the distance, it go awry pretty quick. Applying the cosine to your dope as a percentage gets much better results. Ex: 500 yards @30* down slope. Cosine .866. Don't apply the cosine of .866 to the 500 yards. If your dope is say, 10 moa for 500 yards, then 10 moa x .866 = 8.6 moa [/QUOTE]
