Well so far I have put 30 Barnes a half that many Hornaday DGX through my double . The left barrel shoots the Barnes in one hole , the right in about 1 1/2 group about 1 inch right of the left but both about 5 inches high at 65 yards. I file a little and go shoot six. Off sticks. All this is making me a better shot but it is a little frustrating waking up thinking how to change the bullets for a perfect reg. Damn the work.
