To help you choose the correct choke tube for each
hunting and shooting situation, all Invector-Plus
choke tubes are inscribed on the side with the patterns
they produce with both lead and steel shot. Each
Invector-Plus tube also has notches in the top rim of the
tube (Figure 15). These notches are a code to allow you
to determine the choke designation while the tube is
installed. Rim notches refer specifically to lead shot.
Use the charts on this page to cross-reference from lead
shot to steel shot, and determine the appropriate tubes for
your ammunition and hunting/shooting situation.
Several choke tubes are supplied with your shotgun.
The choke tubes listed are also available as accessories.
Remember, WinChoke, Standard Invector and Invector-
Plus tubes are not interchangeable. Invector-Plus tubes
are for Winchester shotguns with back-bored barrels
only. Before removing or installing tubes, or reading
the rim notch code, make sure your shotgun is
completely unloaded.

All Super X3 shotgun barrels are threaded to accept the
Invector-Plus ™ choke tube system. Standard Invector and
Invector-Plus tubes are not interchangeable. Confirm the
choke system of your shotgun by looking on the right side
of the barrel where the specifications are inscribed, where
the choke markings are normally located.
The constriction of each choke tube is indicated twice on
the choke tube: on the side of the tube, and indicated
with a “notch” code on the top rim of the tube. The
included universal choke tube wrench is used to remove
and install choke tubes.
Invector-Plus and Standard Invector choke tubes are
compatible with factory ammunition that has been
loaded in compliance with SAAMI specifications,
including magnum lead and steel shot loads, sabots and
shotgun slug loads.
Replacement and additional tubes and wrenches are
available from your Winchester Repeating Arms dealer, or
by contacting the Winchester Repeating Arms Customer
Service Department. See page 41 for contact information.

steel shot will result in an ineffective “blown” pattern.
** Extra Full Turkey, extended with ports. Do not use with steel shot.

the more open choke listed for high velocity, larger shot size steel loads.
