I would love to know the pellet counts that you are getting at 40 and 50 in a 10 in. circle using magblend 3.5 and a jellyhead choke.
I think in my 26" Nova with a JH .655 I got 160-180 or so at 40yds. Not great, but it'll hunt.
239 With a JH .690, in a Ol mossy 835 24" Barrel @ 40. Some get up to 250 I've read.
870, .665 JH, 3.5mag blends in the 180-190's 40yds
