Sounds like you are talking about your initial adjustment from when you received your scope??I have a question regarding my recently purchased AT-X in 6.5 Creedmore. For optics I am using a ZCO 840 scope with a 1.5 Spuhr mount. I took it to the range yesterday and and attempted to zero it. My plan was to get it on paper a 50 yards and do my final zero at 100. What surprised me, is that it took 10.5 mils on the turret in elevation to get it on paper at 50 yards and the shots were still low. I find this strange because by other gun, a MPA Hybrid Hunter with a 1.125 Spuhr mount and a Nightforce ATACR 7-35 took only 3.5 mils on the turret elevation to get the gun zeroed at 100 yards. I can't figure out why there is such a discrepancy between both rifles. Now I am wondering if there is a problem with the scope or the AT-X rifle or could the difference be normal due to being different rifles, height of mounts and/or different scopes.
Both of my ZCOs came out of the box with elevation "bottomed" out. My Nightforces have not come this way. You might just be comparing apples to oranges here.
