Leupold Vari X Series Instructions Manual

18
A click for each adjustment division can be both heard and felt so adjustments
to the scope can be made without looking at the dials. Indicators on the
micrometer portion of the dial show the number of complete 360˚ rotations
that have been made. 
BULLET DROP COMPENSATION DIALS
Special bullet drop compensation (BDC) elevation dials are featured on
selected scopes. These dials are calibrated to achieve adjustment to specific
distances rapidly by distance indicators marked directly on the dials....

ZEROING THE WINDAGE AND ELEVATION
DIALS AFTER SIGHTING IN
All Leupold scopes feature adjustment dials, either numbered or with an
indicator, that can be repositioned to align the marked zero of the dial with
the position indicator without changing the adjustment setting of the scope
that was achieved when sighting-in. This allows the shooter to know the original
zero of the rifle in the event that further adjustments are made in the field.
To reposition the dials on VX
TM-I and Fixed Power models,...

20
VX-II and Vari-X III models have a pointer dial that moves with the
adjustment slot. This dial also can be moved independently to align with the
zero on the outermost dial. To reposition this dial simply rotate it until the
pointer is aligned with the zero.
To reposition the dials on Target and Tactical models:
1.
Loosen the set screws that surround the top of the knob until the cylinder
turns freely. 
2.
Move the cylinder dial by hand to align the zero with the white 
perpendicular mark at the base...

CENTERING WINDAGE AND ELEVATION ADJUSTMENTS
TO ACHIEVE OPTIMUM ADJUSTMENT TRAVELMaking windage and elevation adjustments moves the entire erector system
horizontally and vertically inside the scope. If the erector system is off to one
side – as a result of having been mounted on a non-adjustable mount – the
adjustments won’t provide equal travel in all directions. To regain full balanced
travel, you must recenter the adjustment as follows:
1.
Turn the windage adjustment to the point that it stops...

hat you should know 
about variable power scopes
]
Leupold variable power scopes allow you to select from a range of magnifi-
cations to suit your particular rifle, cartridge, and shooting needs.
WARNING:Do not loosen the screw in the power selector ring. 
Doing so will release the internal nitrogen that keeps the scope fog-free.
Loosening the screw will also disconnect a pin that controls the internal
operations, causing other problems that would require factory repairs. 
Do not lubricate the...

RANGE ESTIMATING WITH
VARI
-X III 
SCOPES
Selected Vari-X III scopes have a built-in range estimator. This system uses
the Duplex
®reticle in combination with an additional set of numbers on 
the power selector ring. In scopes with this feature the space between the tip
of the thicker post of the Duplex reticle and the center of the reticle covers
16 inches at 200 yards (the size of a Whitetail buck from backbone to brisket).
NOTE:The Duplex reticle was designed to estimate ranges based on the back-...

24
Bracket the animal from 
backbone to brisket.
On scopes with this feature, the numbers facing forward show the scope’s
magnification settings. The numbers facing the back are for ranging and
show the distances in yards, as shown in Figure F.
To estimate range, follow these steps:
1.
View the target through the scope.
2.
When targeting an animal with a body that is 16 inches from backbone
to brisket, adjust the power selector until that area of the animal’s body
fits between the center of the crosshair...

UNDERSTANDING PARALLAX
Parallax is the apparent movement of the target relative to the reticle when
you move your eye away from the center point of the eyepiece. It occurs
when the target does not fall on the same optical plane as the reticle.
Maximum parallax occurs when your eye is at the very edge of the exit
pupil. (Even in this unlikely event, our 4x hunting scope focused for 150
yards has a maximum error of only 8/10ths of an inch at 500 yards.)
At short distances, the parallax effect does not...

Leupold Compact RF Special scopes are set to be parallax-free at 60 yards.
2.
Leupold Shotgun scopes are set to be parallax-free at 75 yards.
3.
Leupold Handgun (EER) and Compact 2.5x scopes are set to be 
parallax-free at 100 yards.
4.
Leupold Turkey Ranger scopes are set to be parallax-free at 40 yards.
THE ADVANTAGE OF ADJUSTABLE
PARALLAX SETTING SCOPES
Target shooting and varmint hunting demand extreme accuracy. You must
have a scope with a parallax adjustment dial for precise shooting at...

27
The parallax adjustment can be located either at the objective end of the
scope or on the side of the adjustment turret housing. The adjustment moves
a lens within the scope causing the image and the reticle to fall on the same
optical plane. This ensures optimal accuracy at the distance of the target.
To eliminate parallax in adjustable objective scopes, follow these steps:
1.
The reticle should be clear (focused) before adjusting the focus ring. 
If it is not, follow the instructions under “Focusing...
