I'm a fan of ported chokes from Rhino. They are expensive but well built and work good in every shotgun I have seen(including Mossberg). It has been my experience that buckshot does not shoot good out of the super full turkey chokes.

................You really might want to try a load of buckshot thru it at a target and see how it patterns for you. Buckshot size, choke size, all add to the variables. As was previously mentioned I doubt that it's gonna pattern well with that choke....but try it or you'll never know.
