Forgive me if this sounds like lecturing. Trap, Skeet, and Sporting Clays are all specific games, with specific rules. The ideal gun requirements vary for those games. Look them up for more info.
That is not to say there is anything wrong with going out in a pasture and shooting clay pigeons. It's great; I have a machine and do it all the time. But it is not either of those games. It is shooting clay pigeons. The only reason I point this out is it matters a lot when asking for advice. For example, shooting "doubles" off a manual thrower may be about as difficult as you can get, because that right hand bird doesn't stay in the air very long, and it is close enough to need an open choke, and if you shoot it first, you probably need more choke for the other target by the time you get on it. Fine if you have a good two barreled gun, but not for us single barrel guys.
