[QUOTE="Darryl Cassel, post: 203, member: 34"] Lets make this simple to understand and round off the differance. A MOA is not really one inch but, for explaining this, I will use the 1 inch method, which is real close. 1" is one minute of angle (MOA) at 100 yds. 2" is one MOA at 200 yds 3" is one MOA at 300 yds 4" is one MOA at 400 yds 5" is one MOA at 500 yds and so on. For each 100 yds the MOA goes up accordingly. If you shot a 2" group at 300 yds that would be two thirds of a MOA at that distance (300 yds) which is .666 MOA . 2/3= .666 after you divide. To give added info ---At 1000 yards a 10" group is one MOA. Each click with a 1/4 Min scope will change bullet impact(Elevation or windage) 1/4" at 100 yds. At 200 yds each click will move impact 1/2".At 300 yards 3/4" At 400 yds 1"---At 1000 yards 10 X 1/4"= 2 1/2" of impact change. At 2000 yds 20 X 1/4" = 5" of impact change for EACH click of your scope. Get a ballistics program for your computer like the Oehler and run the different yardages you intend to shoot. It will give you a complete printout for anything you want to know. Hope this helped you. DC [img]images/icons/smile.gif[/img] [ 06-05-2001: Message edited by: Darryl Cassel ] [/QUOTE]
