Home Forums Hunting & Shooting Hunting Rifles What on Gods green earth? VX-3

I have 26 Leupolds, but I am only intimately acquainted with half of them.

The only problem I have seen with aiming was a temporary backlash in windage on a Mark IV 8.5x25x50.
That is like backlash on a mill, a lathe, or a guitar tuning machine head.
In the M55, my father designed a split gear spring loaded that eliminated the backlash in aiming. That is in a worm gear. But the Leupold is good enough with two turrets and a spring to usually keep backlash out of the turret screw. If you ever did have backlash, back off counter clockwise and work up to the adjustment clockwise, like you would when tuning a guitar.

I take tools and fix my rifle builds and fix other people's problems at the range. More than half the time my problem and other people's problem is loose screws that fasten the base to the receiver.
The symptom is two shots over there, and two shots over there.
I don't know why it is never the ring cap screws.
I don't know why it is never the rings to base clamp.
I don't know why it is never the scope that failed.

Sometimes the scope was not mounted close enough to parallel with the bore, and the scope runs out of range before windage or elevation can sight it in.

The point is.. it is almost always those base to receiver screws.
Clean them. Clean the female threads in the receiver. Put loctite in them. Torque them.
