Fudd, I'm guessing you rezeroed the suspect load at 200 to find the 2" peak at 125? If you did, I suspect it was because you found it low at 200 at compared to the first batch zero?
Indeed but I have never seen a rifle that shot lower with a faster load than with a slower, have you?

Were it not for the zero confirmation of the lower velocity I would have suspected that he had fallen foul of the chrony not be fully folded out for the first batch.

He must have rezeroed to get the higher maximum ordinate.
