[QUOTE="merbeau, post: 1550785, member: 38494"] Hi I have been shooting in local 600 yd matches and am wanting to start competing at 1,000 yards. To do that I purchased a Nightforce 20 moa base. If I understand this concept, the 20 moa base means the rifle will be 20 inches high at 100 yards. So the rifle has to come down 20 inches to be zeroed at 100 yds which frees up more scope movement upward for longer shots. Using this formula [I]Scope Clicks = (amount of desired bullet impact location movement / amount of scope movement per click) x (adjustment distance specified on the scope / distance to the target). For my scope coming down 20 inches would be 160[/I] clicks. I have 70 clicks per revolution of the scope's elevation turret. So that meas ~ 2.2 revolutions. Went to the range using the above strategy and fired 10 rounds and never could see where the bullet was hitting. Definitely not on the target. What am I missing? Thanks Robert [/QUOTE]
