That sounds like a really good deal to me. Being .690 my first choice would probably be Longbeards in number 4 or 5 shot. I also have a 835 with a Stardot .676 in it. It shoots about everything well. If the .690 doesn't work out I'd look at chokes in the .676.-.670 range. Theres alot of good ones out there. One things for sure never seen a 835 that wouldn't shoot.Good luck
