90 yards is a pretty good poke for a deer slug, let alone a turkey shell[8D]

Back to the topic....I had an 835 with a factory full choke...it like #4's winchester surpeme 3 1/2's.....it did kick like mad, but patterned well to 45 yards. But like others have said....shoot as many shells and chokes as it takes to find a combo that pleases you.
