This set of choke tubes have one used Modified choke and the full and extra full are not used never shot. A MTM case is included. I have used the modified as that did what I needed. It was both hunted with and used very lightly with some light target loads number 8 lead shot. No shot larger than number 2 steel was ever used in it. Only reason I am selling this set is because I am no longer shooting the way I used to hunt and have changed shotguns. The full and extra full are new and have never been installed in the shotgun selling as a set as that’s how I purchased them.
