Right Wrong
The diagrams above show what the relationship between the
sight and the barrel should be.
1) Place the gun vice or workmate on a firm and level
surface.
2) Clamp the rifle, making sure that you do not damage the
stock.
3) Place one spirit level across the flat part of the breechblock
and adjust the rifle until it is level.
4) Now look through the sight and without moving the rifle
rotate the scope until the vertical cross hair aligns with the
plumb line.
5) All screws should now be tightened. BKL mounts
breechblock securing screws should be tensioned just over
¼ of a turn or 49 lb/in torque.
Adjusting the zero:
Set up a large paper target, with a safe and suitable backstop
at around 12yds.
1) Mark a simple cross on the target and from about 12 yds.
Fire a test shot.
2) If the pellet is close to the ‘mark’ then note its position.

3) If the shot was lower than 5 inches then you will probably
run out of adjustment on the elevation turret and it will be
necessary to pack up the back of the scope.
4) Using the turrets on your scope, adjust until the centre of
the crosshair and the pellet hole coincide.
5) Repeat stages 1-4 at your chosen zeroing distance.
NOTE:
It is quite common when sighting in an airgun to need to tilt the
scope forward by shimming the rear mount. A good material to
use for this purpose is 35mm film negative and you should only
need to use 1-2 pieces. Simply cut the negative to the same size
as the mount and place it under the scope in the rearmost
mount. This does mean that you will have to remove the clamps
and repeat the alignment procedure. However if the masking
tape is still on the scope tube then this will allow you to remove
the scope and refit it and still have the correct eye relief.
Safe Shooting Ranges.
Safety must be your main priority when setting up a shooting
range. Whether it be in your garden, a friendly farmers field, or
even in your attic space, thought must be given to where the
pellet is going to finish up, and what might cause it to deviate
from its intended path. A modern air rifle is capable of shooting
a pellet up to 250 yards and for most shooters, unless you are
shooting in a field this means the shot WILL travel off your
property unless you have taken precautions to prevent it.
The following should give you some ideas and while not a
complete list, will get you thinking “SAFETY”
.
When setting up your range, you must ensure that either:
1) A suitable backstop has been set up to prevent the pellet
from travelling further than you intend. Do not assume that
your garden fence will act as a backstop; it won’t!
