I understand that MOA (minute of angle) means that at 100 yards your shots are in a 1" group, at 200 yards in a 2 inch group and so on. After that, I'm lost.
Did this term originate in the military? Or, is it a term from target competition?
Is 2 MOA a 2 inch group at 100 yards? And, if a gun shoots MOA, does that mean all shots are within a 1" group, on average they're in a 1" group, or ??
I would think the weapons that fire MOA are fairly rare and expensive - seems like a hell of a feat when you're used to being a 'plinker'.
