I don't shoot turkeys unless they are pretty close within 30 yards. So I just use the choke that it comes with. I don't know if Benelli chokes will fit it but I would guess yes if you I was forced to guess. Only because other things that I have bought for it (sights) say Benelli/Stoeger.

The loads that I use are the Winchester #4, #5. Federal #5's printed pretty good too
