They can do the job most likely out to 40, but for the price I would probably shoot a cheaper turkey load. They seem to give me a more even pattern than pheasant shells. I tried them through an old 20 gauge single shot (2 3/4") with factory full and some other pheasant shells through that and my 12 and all were more erratic it seemed than turkey loads, or even just high brass game loads for that matter. I don't know if it is the velocity or what that does it.
