Permanent blinds are usually not a very good idea for turkey hunting, but I have taken multiple birds from the same spot. Pattern them first. I have seen some hunters use one of those pop-up blinds. Normally, you want to be able to change locations and/or setup on the fly depending on the situation. If you use decoys, make sure you are using them where they can be seen from a distance. As for your gun, I have the same gun. It works just fine for turkey.

Other than roost areas and travel routes, I also try to find strut zones. This is sometimes on a point or corner of a wood edge in a field where a tom can strut and be seen by possible hens in multiple directions at large distances. He wants to be seen from as much wood edge as possible. This is where you sit with decoys. Good luck.
