I am putting a Rhino on mine. I gave them my information (12 GA. Encore Turkey Barrel, the shell (Hevi 13 3" #7), and what I was looking for at 35 yards. Don't know if they are gonna ship the .660 or the .670, but I can return one for the other if I am not satisfied with the first. As for ease of carry, handling, etc., I have never held a better turkey gun. I like the gun but just have to find the right recipe.
