"Y0u would think that with the camera directly mounted to the scope that would at least eliminate the possibility of inconsistent eye ball alignment which would be a benefit and then using the view finder to do the aiming would be ideal???. I shot a little this evening and my 60yd poi appeared to have dropped about an inch. I do believe that adding on anything to the gun will change the harmonics, maybe not a lot but some. I think it's going to work great. May have to re-zero a little and go from there."Jimmy,
I think KYairgunner nailed it with his reference to parralax. Consider a scoped rifle placed on sandbags and one is looking at a target. When parralax is not adjusted properly, even looking through the scope may appear clear, when one moves their head around the rear (ocular) lens they will see the cross hairs move relative to the target. So just by moving only one's head and not the rifle, the point of aim moves and the point of impact stays the same. This is called the "head bob" test. If parralax IS adjusted properly, the cross hairs will NOT move relative to the target. So possibly the camera is not mounted to where you would hold your eye. This became an issue and causing a POI due to incorrect parralax setting.
