What is MOA (Minute of Angle)? Its used alot in target shooting and hunting.

In: Physics

There’s 60 minutes in a degree; they’re used when a degree isn’t precise enough.

I know very little about shooting (guns), but I know a lot about math, so that’s my best guess.

MOA describes how far apart your shots are in relation to how far you are from the target. A 3-inch group at 50 yards is much less accurate than a 3-inch group at 500 yards, so by using MOA as the unit, you don’t have to explain how far you were from the target.

The simple explanation is that a minute is a measurement is equal to a 1 inch circle at 100 yards. A 2 inch circle at 200 yards and so forth. So if you fire a gun 10 times and the bullets all are within a 2 inch circle at 200 yards. You have a 1 MOA gun.
