yes rhino is a choke. the one I shoot is like th jelly head. You might consider having the barrell polished, ported, and forcing cone lengthened or trading the gun off. Last option would be to send it to one of the companies that will work up a load, choke combo for your gun and be able to gunsmith on it at the same time. My extrema 2 performs great and I would not trade it for anything. I had those above mentioned mods done and shooting a 3 1/2 inch shell has the same recoil a heavy 2 3/4 does. I ain't scared to pull the trigger on it.
