It clears things up...
“Aggregates for group shooting at 100, 200 and 300 yards are calculated in approximate Minutes of Angle (1 inch = 1 MOA at 100 Yards). Grand Aggregates are figured as an average of the MOA at each distance. Aggregates and Grand Aggregates for 100 and 200 Meter competition are calculated using the same technique. However, it should be realized that these figures will be simple aggregates and are not in MOA. MOA can be derived for the Metric Aggregates by multiplying by .914.”
