    Starting to look as though it is a chrony problem in the bright light which I have seen before. The clincher would be the load. Hodgdon has velocities for a 15 inch barrel which should be close enough for 16 inches. It would seem that it is a light load that is most accurate which might indicate a bedding problem. Something to look into.
