I just got a new laser bore-sighter and decided to see how close it was on my rifle that was just at the range yesterday. It was very close but I noticed something very disturbing when I played with the zoom on my scope. This is a brand new VXIII 8.5-25x50 LRT 30mm scope with the varmint reticle. At 200 yards the cross hairs move up from just under the 200 yard center bulls eye to centered between the 300 and 400 hairs or about 5" vertically in relation to the laser point when I zoom from 8.5 to 25. I haven't confirmed with actual shooting as I never zoom the scope lower than 25 power for shooting. I have a bunch variable scopes and they all live on their highest power. If I ever had to turn the zoom that far down the trajectory is going to change a bunch as well and would need to be compensated for anyway. I will be range testing this later this next weekend. I’m also wondering that since the change is purely vertical that there is some sort of other phenomena here that is explainable. With a variable range I expected the laser to appear higher and lower and it does, but on a fixed range just moving the power ring, I did not expect that much movement. The AO did have any affect on the elevation change as I was holding still and having my son run the zoom and AO so I could watch it move. It didn’t matter exactly what we were aiming at as the relationship that was changing was the crosshair intersection to the where the bore was pointing. I will be testing all my scope eventually especially my 8-32 BD and the scopes on my rim fire rifles as they are the only ones that ever get the power rings moved for shooting. Has anyone ever noticed this before? Is it fixable or really not an issue?
