My axis 308 ss is paired with a Bushnell Banner 4-16x40mm Riflescope with CF500 SFP Reticle with weaver grand slam rings and weaver rail. I first sighted the rifle in at 25 yard stacking hole on top of each other then moved out to 100 yards and all hell broke loose. I would shot and make adjustments and shot would be way off from where I originally shot. And I did have a whole lot of movement from the shot making me get off target. I am using a Caldwell Steady Rest NXT for sighting in. Any help would be appreciated thanks. I'm useing Monarch FMJ .308 Winchester 145-Gr, Tula 308 Winchester Ammunition 165 Grain, Winchester Super-X 150 gr.
