So what is it? BSA barrels?
The only way to reliably test is to shoot at 90 degrees to the wind, then in the same conditions, swing the rifle round to 180 degrees and test again at the same distance.
Alternatively, shoot from firing point to target, then go to target and shoot back to firing point.
Either way you are trying to establish wether it is the rifle/pellet or the scope introducing errors due to cross-over etc.
Velocity and twist rate can have an effect on the windage, but it does depend on the pellet used etc.

Bottom line is that I very much doubt that your rifle takes no wind at all, that just defies ballistics.
