Too vague a question;
-steel shot involved or not?
-upland game only opens the market tremendously
-trap, skeet, clays or hunting?
-many shotguns are set up for RH firing, LH, not as much
-slug shooting or buckshot use a possibility?
-is the user recoil sensitive and wishing for a semi-auto?
-is the user comfortable with a heavy gun or otherwise?
-does the user care to use unusual gauges not commonly found ammo, such as 28, 16 or 10?
-will you be sitting in a ground blind or making tracks all over the hunting fields all day long?
-some shooters use different chokes based on hunting over dogs or otherwise
