Rhino's are excellent, as are Kick's chokes. Will they tighten patterns over a factory choke? Probably so, and, probably significantly so. But ya wanna know a little secret? If it is turkey loads only that you're talking about - the Primos JellyHead chokes will do as well for about 1/5 the cost. It really isn't that big a secret either. Go over to the National Wild Turkey Federation forums and check the threads about the JellyHead or Nitro ammo. I like the Kick's chokes better than the JellyHead because of the personal service Kick's provides, they are beautifully machined and finished, moderately priced, and the Kick's chokes shoot very, very, well. But I'd buy a JellyHead for turkey hunting before I'd shell out $100 for a Rhino.
