[QUOTE="shooter7, post: 2034921, member: 39303"] MO Minute of Angle(MOA) is an angular measurement. When converting into inches at a given distance, it's value will change. At 100 yards the value of 1 MOA is 1.047". At 200 yards 1 MOA is now 2.094". At 300 yards 1 MOA is 3.141". This trend continues indefinitely. Most scopes that are calibrated in MOA offer 1/4 MOA adjustments. This means at any distance each click will move the point of impact 1/4 of a Minute Of Angle. At 300 yards this means each click would have a linear value of .785" Example: If you have a 100 yard zero and you know your trajectory is 14.5 inches low at 300 yards then you do the math. 14.5÷3.141= 4.616 4.616 is how many Minutes of Angle you are low with your 100 yard zero. To raise your impact you would dial 4.5 MOA up on the scope. You would still technically be .116 MOA low but in terms of practical accuracy it is negligible. If you're using a 300 yard zero then your trajectories at 100 and 200 yards will be above your point of aim in your scope. Everything beyond 300 will be low. In terms of practical accuracy on game animals, with most modern cartridges you will still be in the vitals on everything closer than 300 yard without any adjustments. Here's a decent article explaining trajectories and using different zero ranges. [URL unfurl="true"]https://christensenarms.com/blog/where-should-i-zero-my-rifle/[/URL] [/QUOTE]
