I mounted an Optisan 3x12 on an HW95 using Sportsmatch rings. The scope arrived close to optically centered - was verified by mirror method.
Next step was to set up plumb line and at ~ 5 yards and align vertical crosshair. Did this to align bubble level on scope tube with vertical crosshair.
I then set up mirror 5 yards and align vertical crosshairs to centerline of objective lens and muzzle. I must admit that it not not easy to see objective clearly, but it looked close.
FWIW I also had bubble level on dovetail, which was also pretty close.
After snugging all screws down I took outside to have a look. Set up target at 30 yards and leveled grid. When crosshairs aligned with target, scope bubble level is off. If level scope bubble leveled, crosshairs are counterclockwise a few degrees.
Rechecked scope crosshair alignment to plumb bob and scope bubble level matches.
I suspect that scope not aligned to rifle bore resulting in cant error, but what is most sensible way to correct?
I have mounted many scopes on bolt action powder burners successfully and also one PCP. For some reason this springer is not working out.
