Newbie question... Please educate me...

When someone states they are shooting 1 MOA at say 50 meters what does it mean?

Much appreciated...

"One minute of angle"

At 50 yards, it's 1/2".
At 100 yards, it's 1".

Your 3 or 5 or whatever shot group would all fit in a X" circle.

Better yet, Google is a great tool.

Thank you sir...

:)

BTW 1 MOA is applicable only to opticals? Or can you shoot 1 MOA with iron?

[Jimmie]

MOA is just a measurement based on simple trig. You can shoot 1 MOA with a blowgun if you practice enough, I reckon.
