Each Invector-Plus® tube also has notches on the top rim of the tube. 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 on page 24 to cross-reference from lead to steel, and determine the appropriate tubes for your ammunition and hunting/shooting situation.
