Here is a pattern from my 835, just thought it would be cool to see where everyone else is pattern wise. Mine is not the tightest and I had some that were tighter with other chokes, but this one is very even and plenty enough to 50yds. Gotta love them old StarDot's, I know where one more is.
24" old skewl nonported 835
3.5" 2.25oz Hevi13 #6
.676" StarDot choke - $5 choke
43yds
33 degrees - slight wind
170- 10"
298 - 19"
As always better patterns in better weather.
