RE: Rhino/ Nitro Combo?
 

I'll jump in too....you will love the combination. I use one on my BPS 3.5" 12 ga. and it is amazing. I have been using the triplex loads as well.

RE: Rhino/ Nitro Combo?
 

Ditto what everyone has said about the Rhino chokes and Ray's Nitro loads. I used this set up for the first time last year with my Browning BPS and killed three nice longbeards (1 in SC and 2 in WV). I couldn't be happier with the performance in real hunting conditions. Nothing comes close in patterning and nothing knocks 'em down like those Nitro hevi-shot shells.
