SIGHTING-IN, ADJUSTMENT AND GENERAL USE
OF YOUR NEW BSA TARGET SCOPE
The windage and elevation adjustment of a riflescope is intended to allow for left-right and up-down adjustment of the reticle,
to align the riflescope to the target. Although this is a standard feature of any riflescope, many consumers are not aware that it
is common for the windage and elevation movement of a target scope to be less than that of a lower powered “hunting”
scope. However these units are required to have no less than 15 MOA (Minute Of Angle, or approximately 1" at 100 yards;
_____" at 50 yards, etc.) of adjustment in each direction, measured from the mechanical center, and are mechanically centered
at the factory prior to shipping.
There may also be a small amount of travel in the knobs that will not affect any windage or elevation adjustment. This occurs
when the scope has reached its maximum adjustment. Again, this is not uncommon in any riflescope design, but tends to be
more pronounced in a high - powered riflescope with less windage and elevation range. It is not a defect or malfunction of in
the scope.
With this in mind, the importance of precision in mounting the scope becomes clear. However, design differences between
gun manufacturers and their respective models, or the common downward angle of many break-action airgun barrels, also
create the potential for difficulty in scope alignment. Practically speaking, if sighting in at 100 yards and there is more than 15
inches of variation between the point of impact of the shots and the reticle upon first mounting the scope, the scope must be
re-mounted. In these cases, it may become necessary to use an adjustable base or ring set in mounting these scopes.
All BSA Target Scopes have removable W/E turret knobs that can be reset to zero once the rifle has been sighted in. This
feature allows the shooter to calculate how many “clicks” of adjustment are necessary from the zero setting when shooting at
different distances or wind conditions, then quickly and accurately return to their original setting. The knobs can be reset as
follows:
Three small screws (spaced equally around the top of the knob) secure the knob onto the internal post. Once the rifle has
been zeroed at a particular distance (such as 100 yards) the screws can be backed out approximately _ turn each, the knob
pulled straight off, (so as to not alter the actual setting of the scope), and the knob replaced with “0” setting on the indicator
line of the turret drum. Keeping in mind that each click of to knob is equal to ___ MOA, and that this value is different at
different distances (___ at 100 yards, ___" at 200 yards, and 1/16" at 50 yards, and so on), the shooter can calculate how many
clicks are necessary to compensate for the new distance or wind deflection.
It is not uncommon for the image of a high magnification scope to be considered “dark” or “blurry” when being compared to
that of a low powered riflescope.
The brightness and clarity of an image is directly related to several factors. One factor is the diameter of the objective lens: a
larger diameter lens will allow more light to enter the optical system. Another factor is the magnification of the unit. As the
magnification increases, the amount of available light decreases. For example, although the objective diameter of a 6x-24x44
mm riflescope is greater than that of a 3x-9x40 mm riflescope, (44 mm as compared to 40 mm), the magnification is
significantly increased (6x-24 as compared to 3x-9x). This disproportionate variation in these two factors will result in the
target scopes having an apparently darker overall image than the standard riflescope. This is not uncommon, and does not
signify any malfunction in the optical system of this unit.
