I have owned the original 835, the 935 auto and now the new 835 tactical. Many/most of my friends have the 835/935 and the best chokes are the kicks, jellyhead and my personal favorite the comp-n-choke. My comp'n'choke is the xxx full and I shoot winchester turkey loads in 3.5'/#5 1/4oz shot and it patterns great. the only thing is that when the bird is 10-15 yards you better be aiming at the base of the neck because the pattern is the size of a baseball at that distance. 20-50 yards it absolutely crushes birds! I never had to shoot at a bird over 30 but I am confident that if you hunt field edges you will dust them at 50+. Throw a Simmons pro-diamond or same type recticle scope on there and you will be in business. I hope this helps you out and good luck on all of your future hunts.
