[QUOTE="trebark, post: 332685, member: 19172"] The trouble you're running into here is the difference between what the 'book' says and reality. What you need to do is some trajectory validation. Zero your rifle at 100 yards. Then whatever you 'book' says to adjust for 200 yards, make that scope adjustment and shoot a 200 yard group. Then make the 300 yard adjustment according to your 'book' and shoot a group, then 400, 600 and so on. Then go out and measure the difference between the 'book' and the reality. You can now calculate your trajectory and have accurate adjustments for your various distances. Of course, once you have this validated trajectory, you will have to go out again and check it...just to be sure. [/QUOTE]
