Go back to the basics. IMHO,,, I would go back to the hornady ammo that shot 3/4" for you before. Then I would place a target downrange & center the crosshairs on a known area of the target such as the center of something that is easy to go back to. Set the scope adjustment off in elevation & windage a small known value, such as 6-clicks each way. Now put the cross hairs on the first reference point & fire a three or five shot group, keeping the scope centered on the reference point each shot. Your POI will be off but you will see the group. Aiming at at the center of a unshot reference point is easier than aiming for the center of a hole you previously shot. If you do your part, this should tell you if the scope is performing.
