So went out and shot the first groups using US869 in the 26 Nosler. The right group was first and showed promise. I adjusted the scope over left and down as I want it 0.5” high at 100. The middle group was next. Seemed to over adjust and now groups left of center. Not to mention the down adjust did not work. So I went right and down to get centered and shot the last group on the far left. Which is totally backwards to my adjustment. I quit wasting my time at this point. The scope is a Zeiss 4.5-14 conquest. An older scope but I had no issues with it till now. Or so I think. Will look back at some notes in the reloading binder. Anyone have any ideas other than a new scope? Mounts are good. Rifle is Browning.
