wondering who all shoots full choke for ducks and geese, reguardless of gauge? I shoot a full choke (terror) in my gold 10, shoot an improved modified (Carlson thin wall) out of my Auto 5, 12 gauge. I have an Auto 5 mag 20 gauge with a Carlson full choke and it seems to pattern 3's and 4's very well. I'd like to use it this year with some Kent ammo. Buying a modified of light modified is not a problem, cause they're only about $18. Over the years I've tended to shoot an improved modified or full for most everything but, it seems that very few on the forums do, for ducks.
