The program wants to know the number of MOA it took to get through half of the reticle field and count the number of clicks it takes you to get from the blue line to the middle long black line (basically 1/2 of the reticle height). just point the fixed/stable rifle at a single point or dot on the target. it's really important the the target is as close to perfectly vertical/plum as possible. Now, if you set the target out at 100 yards and make sure it's plum (you can use a bubble measure to the target or just hang a string with a weight on it to dangle directly on one of the vertical lines) you'll be in great shape to measure. Perhaps the easiest way to do this is to draw out a standard grid on a plain piece of paper to be used as a target.let's say a 30 inches by 30 inches grid (or whatever fits your target area size) marking out each should look just like a regular grid paper looks albeit bigger so you can see it at 100 yards and have enough lines to do a measurement. While often the manual affords you this info, sometimes the individual scope isn't perfect and as such measuring it as i'm describing will hopefully gives you a more reliable measurement. So we know that 1 inch (or more accurately 1.047 inch) equals 1 MOA at 100 yardsĪnd we know that each click of your elevation turret is 1/4 MOA or 1/4 inch at 100 yards per the manufacturer and designer of the reticle.
