Tall Target Test

I think he said to adjust the level on the scope

I am thinking adjusting the level on the scope means rotating the scope until it's level. Apart from pushing it forward backwards the only thing you can do is rotate it in the rings.

To avoid second guessing what Brian means I put it to you there are three things that need to be level for us to believe any variation from the expected is down to a lack of calibration:

1. The scope axis must be absolutely vertical to the bore axis when shooting (i.e. no canting the gun).
2. The erector mechanism connected to the windage/elevation knobs needs to be
absolutely vertical/horizontal to 1.
3. The reticle needs to be absolutely vertical/horizontal to 2 and 1.

I have separated 2 and 3 because it is unwise to assume the reticle is perfectly aligned with the windage/elevation turrets. I have seen this twice with Leupold MRT scopes (replaced under warranty without fuss).
