Winchester Repeating Arms X Pump (SXP) - Manual (Page 16)

The most certain way to bulge or rupture a shotgun barrel
is to load a smaller gauge shell into a larger gauge chamber.
The smaller gauge shell will not fall completely through
the barrel; its rim is caught by the front of a larger gauge
chamber or at the larger gauge’s choke. Your shotgun will
misfire (with the chamber appearing to be empty). It is
then possible to load the correct gauge shell behind the
smaller gauge shell. If the shotgun is then fired, the result
will be a so-called “12-20, 20-28 or 28-.410 burst” which
can cause extensive damage to your shotgun and possible
serious injury to you and others.
We can assume no responsibility for incidents which occur
through the use of shells of nonstandard dimension or
those developing pressures in excess of SAAMI (Sporting
Arms and Ammunition Manufacturers’ Institute)
established standards.
All current 12 and 20 gauge Super X Pumps have a 3"
chamber and are designed to shoot all factory 2¾" and 3"
Field and Target loads. The barrel can safely handle both
lead and steel shot. Special rifled choke tubes are designed
for shooting sabot-type slugs.

With the magazine three-shot adapter (plug) removed,
your shotgun holds four 2¾" or 3" shells in the magazine.
SXP models with an extended magazine hold six 2¾" or 3"
shells in the magazine. At a range or other suitable
shooting location, load the magazine to full capacity to
verify the number of shells.
Remember, “total” capacity includes an additional shell in
the chamber in addition to a full magazine.

The Super X Pump shotgun is delivered with the magazine
three-shot adapter (plug) installed in the magazine,
limiting magazine capacity to two shells in compliance
with federal migratory bird regulations. If you do not wish
to be limited to three shots when it is not required by law,
you can remove the three-shot adapter.
