INVECTOR TUBE IDENTIFICATION —
To identify individual Invector tubes, refer to the abbreviated
indications on the side of the tube, or use the identification notches
located on the top rim of each tube. (Figures 26 and 27).
SELECTING THE CORRECT INVECTOR CHOKE TUBE —
Although your BT-99 is designed solely for target use with lead shot
loads, the Invector choke system is fully compatible with factory steel
shot loads as well. For your information only, on the chart below 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 inscribed on each choke
tube. Remember, you will only need to refer to the lead shot
