can u use other brands of choke tubes and still get good results with the ammo?

You can use another choke and get good results if not better. What the Nitro folks have done though is test the Rhino chokes in various guns and found what works best with each. With that said, even if you follow their recommendations, every gun is different and the Nitro recommendation may not be the best for your gun. If you want to try something different, you may want to start with a choke that has the same constriction as the Rhino choke that Nitro recommends for you gun.

WM, and the best part is no more searching!! So spread that $200.00 out over 10 years, and it's only $20.00 a year, or the cost of a box call!!

Nitro and Rhino, just do it ! Follow the recomendations for your gun and you won't regret it.

That's what I shoot-10 ga Browning Gold NWTF version ,24"bbl, Rhino .720 choke,Nitro H210 Hevi shot loads. What Nitro load do you shoot??

I shoot either an 870 Super Mag 12 ga. with a Rhino .660 or a BPS 10 ga with a Rhino .720, I shoot #5 Nitro-Hevi's in both and they are far above anything I have ever tried.
