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.

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.

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.

steel shot will result in an ineffective “blown” pattern.

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