Tim, Welcome to the LC Smith forum. The graduated gauge will get you in the ball park, but you need to try and see if someone has a "Skeets" Choke gauge. This is an actual machinist tool made specifically to measure the entire choke in a very precise way. If you want to invest in one Midway- USA has them.
