I'm going to experiment with different hunting and clays loads and 2 or 3 different extended choke tubes in a browning citori (inv +). Is there any distinctions/preferences between Briley, Trulock, and Carlsons? Should I see much improvement over the browning flush fit chokes?
For Clays - go extended for quick easy changes between stations.
For pairs target presentation, I would suggest 2 x Skeet, and 2 x Light Modified
( aka Skeet 2, or sometimes called Improved Skeet) .
Also, Try 1 each of IC, Modified, Improved Modified etc. in whatever brand you choose. I've had good success with all of those brands mentioned on various Sporting guns.
Diffusers have some use on those short range incoming targets that even skeet, or cylinder is too tight for !
