justice,
I have a benelli SBE and seemed to have a similar problem when it was brand new. They told me to fire a box of 3.5 inch out of it and now I can shoot anything from low recoil 1 1/8 oz, 2 3/4 in dove loads right on up to the big 3.5 in tungsten. But if I were going to get a turkey gun, I think I would look at a 10 ga. I have a 10 ga BPS with a browing extended turkey choke that will really reach out there. The recoil is a little heavier, but not that bad considering the shotgun weighs about 10lbs.
