| Seeing as how there is no sticky, can someone explain the MOA concept to me? |

Here is a good guide. and another edited to fix second link |

I'll give a cliff's notes rundown:
"MOA" = Minute of Angle A circle has 360 degrees. A degree can be divided into 60 minutes (in this case "minutes" = a unit of measurement, not time). A minute can be further divided into 60 seconds. (yeah, I know, makes the time thing even more confusing, just go with it). Now, here's the kicker: As luck would have it, at 100 yards, 1 minute of angle (1/60th of 1/360th of a circle) is approximately 1 inch. Due to the nature of circles, 1 MOA = 2 inches (approx.) at 200 yards 1MOA = 3 inches at 300 yards. 5 inches at 500 yards. 1/2 inch at 50 yards 1/4 inch at 25 yards (or 1/4 of 100 yards - get it?). 2 MOA = 2 inches at 100 yards 6 inches at 300 yards 10 inches at 500 yards 1 inch at 50 yards 1/2 inch at 25 yards. 3 MOA = 3 inches at 100 yards 9 inches at 300 yards 15 inches at 500 yards 1.5 inches at 50 yards 3/4 inch at 25 yards. 1/2 MOA = 1/2 inch at 100 yards 1.5 inches at 300 yards 2.5 inches at 500 yards 1/4 inch at 50 yards 1/8 inch at 25 yards. Hope this helps. |
