tobnpr, there's several ways to define the accuracy of a rifle as well as ways to determine it. One method is whatever ends up with the smallest numerical definition; i.e., smallest few-shot group fired. Another's at the other end of the measuring type spectrum; extreme spread of several dozen shots fired.

Either one could be observed in shooting 200 shots in a group. Three of them fired in succession may well be 1/4 MOA; that happens. Yet the extreme spread of all 200 is 2 MOA.
