[QUOTE="Jeff In TX, post: 17421, member: 1522"] Folks, The real question is how accurate is a cosine indicator out past 300 yards. As for reading wind, I'll agree with you. You better understand wind if you want to shoot long distances, say over 400 yards. The only way to get good at is to practice, practice and practice even more. Shooting angles is the same thing. Just because you have the wind figured out, doesn't mean you have the angle worked out. Shooting a 35 degree angle at 600 yards is roughly a 540 yard shot using a cosine angle. The time of flight of the bullet will actually be longer than flat 540 yards shot. So would you trust a cosine indicator for a shot like this?? That's the real question? Happy Turkey everyone.
