Test that it returns to zero. Same left /right.

Why shoot?

Yep, IMO only way to do it i.e. statically, no shooting. After all you are only wanting to test the scope at this stage not the loads or the shooter's ability. Although having said that some faults in scopes may not show until wound to their extremities and require recoil to show up issue. But that is a different topic altogether.

I do the same as @6x47 posted. I have a chart made up of 2 A3 sheets joined together. The charts are printed accurately by using a cad program with the grid set at 1 MOA (1.047"). Some printers don’t always replicate the cad dimensions so there may be a need to fudge to get the correct result on paper. Some printers also may not give a linear result thru the total grid but as long as you have an accurate end point she should be good as. The two A3s joined together gives me 30 MOA to check with which should be adequate for the most shooting out to 1000 yds. I do a mid point check as well.

The range (100yds) I initially measured using a quality steel tape - only did that once. Happy now to believe my Zeiss rangefinder.

Yes, errors can creep in at each stage but still better than not knowing your scope’s true value. Even some of the top quality scopes can be out.
