Spaniel Posted April 4, 2009 Report Share Posted April 4, 2009 As you may know from your school math's there are 360 degrees in a circle and the degree is also subdivided into 60 minutes. (OK I can get my head around this part) If you draw an angle of 1 minute the distance between the arms at 100 yards will be 1.0475 inches. So at a range of 100 yards with 1/4 minute stops on the adjusters then one click will move the shots by 1/4 of an inch. (Still there just about) Now we can calculate the number of clicks needed to move shots onto the target. For an air rifle a zero range of 25 yards is probably ideal, at this range one minute of arc is 1/4 inch, so for a 1/4 minute adjustment at 25 yards you need 16 clicks to move the shots one inch.(Now Im Lost) Can anyone explain this please as simple as possible would be great Cheers Ian Quote Link to comment Share on other sites More sharing options...
Spaniel Posted April 4, 2009 Author Report Share Posted April 4, 2009 I have zeroed the scope in at 35 yds and the difference between this and then shooting at 25yds is about 4 inches on the target, which is appox 20 clicks on the Vertical adjustment. Is this about right and from a field point of view how or what would you do to judge the distance before taking a shot Cheers Quote Link to comment Share on other sites More sharing options...
mikee Posted April 4, 2009 Report Share Posted April 4, 2009 its quite simple, the minute of angle stays the same but the distance between the rays (arms) reduces as it nears the center point, 0"at 0yds, 1/16" at 25yds, 1/8"at 50yds, 3/16 at 75yds, 1/4" at 100yds, 1/2"at 200yds and so on to infinity mikee Quote Link to comment Share on other sites More sharing options...

Is that right Quote Link to comment Share on other sites More sharing options...
