Winchester Repeating Arms 9410 Top Tang Safety (Historic Manual) - Manual (Page 28)

Care should be taken not to mar the finish, damage
the attaching screws or bend sight components when
adjustments are made.
All sight adjustments are a matter of trial and error.
Remember, it is usually necessary to reset your sights
when you change type or even brand of ammunition.
S IGHT M AINTENANCE —
Occasionally check your sights to make sure they have
not been jarred or vibrated out of adjustment. This is
especially important after extensive shooting or after
hunting under rugged conditions. If so equipped, check
the two screws holding the rear sight blade in place on
the blade mount and carefully tighten if necessary. Check
the screw holding the front sight base to the barrel. This
screw can be accessed by gently removing the fiber optic
pipe from the base. Tighten the screw and carefully
re-install fiber optic pipe. Front and rear sight bases
should always be tight on the barrel and dove-tails
should be snug.
S IGHT PICTURE —
The correct sight picture for the sights on your 9410
when shooting Foster-type slugs is with the front bead
resting in the bottom of the sight blade (also called the
apex of the shallow). The bead itself should rest directly
under the point of impact (Figure 22). For example, if
you were shooting a conventional target, the round, black
bull’s-eye would appear to rest on top of the front bead.
When patterning with birdshot, the sights should be
aligned with the center of the pattern (Figure 23). Some
shooters may wish to position the pattern a few inches
higher than the point of aim, depending on preference
and shooting situation.
