I understand what a minute of angle (MOA) is. And I understand that, at 100 yards, 1 MOA is approximately 1 inch, 2 MOA is approximately 2 inches, etc.
But when someone says they "shot a 2 MOA group at 100 yards," for example, are they saying they shot a circular group with a radius of 2 inches or a diameter of 2 inches?
I believe the correct answer is "diameter." But why is that? Why isn't it radius?
Let's say I'm aiming for the bulls eye, and all my shots are scattered around the bulls eye. My maximum error is the hole farthest away from the bulls eye, correct? If that's true, shouldn't MOA error be defined in terms of radius instead of diameter?
