The Invector-Plus choke system is fully compatible with
factory lead or steel shot loads. The conversion chart
includes both lead and steel shot information. Lead and
steel shot perform differently in tubes with the same
choke constriction. For this reason, both lead and steel
designations have proven necessary. In fact, even larger
steel shot diameters result in different patterns than small-
er steel shot sizes. Each designation is inscribed on each
choke tube.
To help you choose the correct choke tube for each target
shooting and hunting situation, all Invector-Plus choke
tubes are inscribed on the side with abbreviations for the
patterns they produce with both lead and steel shot.
Each tube also features identification notches located on
the top rim of each tube (see Figure 25 and 26). 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. You will need to use the chart
below to cross-reference from lead to steel, and determine
the appropriate tubes for your ammunition and
hunting/shooting situation.
