I was accused of this several years ago by an open class shooter. I was using a timberline crosshair sight with 4 crosshairs, 20, 30, 40, and 50. I have since went to scope myself and the accuser is out of 3-d. Maybe the fact that I was winning and he was not had something to do with his questioning my scores ? It seems to me that this would be very hard to do with the different sizes of the targets ? Why not limit the number of pins ? I can't see why anyone needs more than 4 although I know alot of sights come with 5. Anymore than this and I say eliminate them from the sight.
