A 4 MOA standard results in a cone that covers vital zones to 200m and torso hits to 425m. At 600m, the same 4 MOA cone produces a 70% probability of hit if the shooter uses the correct holds for complex engagements (considering winds and distance- movers are another challenge). The average trained individual who maintains a 4 MOA shot group has a 50% probability of hit to 850m if using proper holds. Teaching holds is admittedly a deeper level of training and education than is common today, but it’s far from impossible. Add the technological aids listed in the capabilities requirements for the next gen optic and the effective range stretches to 141% of the requirement simply by requiring shooters to consistently produce better shot groups.
