He is right , Federal does say , your not supposed to shoot it through a ported choke tube , but people do .....do it all the time
The rhino looks like a kicks , with the circular ports near the muzzle , but it's not - the kicks has the ports within the parallel section , and the rhino has ports within the forcing/constriction area of the choke - both are stout , and constructed with stainless grade steel , use at own risk
Indian Creek warns not to shoot that shell through their popular version of their ported choke
If it were my shotgun , and I wanted to shoot the federals - I would get the Trulock hw choke , it's specifically made for that shell , I think it's a 39$ choke - the only reason I tried those chokes , is because it was tried before and Trulock doesn't make a specific choke for that shell / gun combo
There are other chokes that shoot the federal hw well also , please be safe - Shannon
