SELECTING THE CORRECT INVECTOR CHOKE TUBE —

Although your Citori Plus is designed for target use clean.

BEFORE PERFORMING ANY CLEANING PROCEDURES, ALWAYS MAKE CERTAIN THERE ARE NO SHELLS IN THE CHAMBERS.

with lead shot loads, the Invector Plus choke system is fully compatible with factory steel shot loads as well. For your information only, on the chart above we have included steel shot information in addition to the lead shot choke/pattern specifications you will need. Both lead and steel designations have proven necessary for hunters using other Browning guns with standard Invector and Invector Plus tubes because in any given tube, steel shot gives a different pattern than lead shot. In fact, even larger steel shot diameters result in different patterns than smaller steel shot sizes. Each designation is in-scribed on each choke tul>e. Remember; you will only need to refer to the lead shot designations when selecting a proper tube for your Citori Plus, as your new shotgun is not designed for any hunting use.
