You probably know this but minute of angle is 1/60 of one degree of angle and there is 360 degrees in a circle.
It works out that at 100 yards 1MOA is slightly greater than 1", close to 1.05" if I recall correctly.
Minute of deer or minute of elk - has a meaning of??
Good enough to hit the vitals of the deer or elk at teh distance/position/wind you are dealing with.
Though I hate any gun thats not sub MOA, I still know enough to know that MOA is not required for most situations...
