MOA is angular and is roughly 3" at 300. So 0.4 x 3 = 1.2" or so, which is about the size of the group on that target.
I might have exaggerated slightly. And should have put inch vs moa. My bad.
Center to center its under 3/4" (assuming the big squares are 1"). 300 yards moa would be 3.141 inches.
So worst case .25 moa. Still pretty dang impressive.
