I would be interested in your findings. I just bought a 20" 835 and have a Jellyhead on the way. I will probably just keep hunting with my Encore until I get a chance to pattern the 835.
Do most people shoot 3.5" from the 835s? I have killed about 25 turkeys and all have been with 3" shells. Is the pattern improvement worth the recoil (not so worried about my shoulder, but it has to be harder on the Fastfire over time). Are there other advantages that I am missing? Of the turkeys I have killed only about 3 or 4 total have been closer than 20 yards OR farther than 40 yards. So, about 90% of my hunting opportunities will probably continue to be between 20-40 yards. Are people using the 3.5" shells just in case they misjudge distance and need a little extra security, or is it because 200 in 10" isn't good enough when you can get 300? I have to admit that 300 would give you a ton of confidence on a 'normal' 30ish yard shot!
The most I have ever put up is 220ish with my 20" encore with 3" MagBlends, which I think is awesome for a gun that is 35" long and weighs less than 6 pounds.
Sorry if I hijacked the thread
