grit, grime, oil, cleaning patches or other materials in or
around the action area or in the chambers or bores of the
barrels.
CAUTION: EVEN THE SMALLEST OBSTRUCTION CAN
INCREASE BARREL PRESSURE. THIS MAY RESULT IN
BARREL DAMAGE AND SERIOUS INJURY TO THE
SHOOTER AND OTHERS IN THE VICINITY.

fire. Make sure they are fully forward in the chamber(s),
with the rims in direct contact with the edge of the
extractors/ejectors (See Figure 14).
CAUTION: MAKE SURE THE SHELLS ARE OF THE
PROPER GAUGE AND CHAMBER LENGTH FOR YOUR
GUN. CHECK THE AMMUNITION DESIGNATION ON THE
BARREL AND CHECK THE DESIGNATION ON YOUR
AMMUNITION. FAILURE TO FOLLOW THESE INSTRUC-
TIONS CAN RESULT IN SEVERE DAMAGE TO YOUR
GUN AND POSSIBLE SERIOUS INJURY TO YOURSELF
OR OTHERS.

action is fully closed (See Figure 15).

manship of your shotgun, that the top lever will be just
slightly right of center, even when the action is fully
closed (See Figure 16). This is the result of tight
