I can't tell you anything about the Rhino Choke. But I can tell you Nitro makes some very good turkey loads for most all guns. They do their own testing of various guns & loads to get a perfect match. I took my plain jane Mossberg 500 12ga. Put a xxfull mossberg choke on it, and only got decent patterns with it out to 30yds. I bought some nitro loads they recommended for my gun, and holy moly. 40 some pellets in the head at 35yds. Its great stuff. www.nitrocompany.com It took me awhile to get through, and they are swamped this time of year with orders. Its better to order earlier. But the wait is well worth the product.
