I want to let everybody know what kind of jokes these chokes are. They are manufactured from 4130 steel which is inferior compared to 17-4ph SS used by most of the well-known choke manufactures. Now, the other guys at least warn you not to use steel shot higher than a certain speed with their IM or light full chokes (or no shot bigger than BBís). Jeff instead promises you everything until he has your money and start explaining BS when the choke gets stuck in the barrel. A rogue thatís what he is.
I know it, because I ruined a new Benelli barrel with a 0.675 choke Ė after only one day of hunt with 1650fps #1 Kent rounds.
