I traded off my 835 and now it's time to get rid of my choke.  :(  I tried everyway in the world to find a choke that would out shoot this one but I never could.  From what I can tell it's a Star Dot, ports go all the way around, straight knurl on the end.  I don't see me owning another 835 or I would keep it and it needs to go to someone that will put it to use.
Here is how it shot for me:  http://oldgobbler.com/Forum/index.php/topic,17779.msg196054.html#msg196054
