You can not shoot wildfowl with an FAC shotgun. The WCA also precludes their use elsewhere - such as making it illegal to shoot a hedgehog with one !
I really think the OP needs to do a bit more homework. I imagine requesting a Sec 1 shotgun for anything other than Practical on an initial application would be tricky as usually it takes a landowner's letter to an existing SGC holder doing pest control for such a grant to succeed. Frankly having grown up in the days of 5-shot repeaters I just would not use anything of higher capacity for quarry shooting. I think you would have to have "game" listed on your certificate to use a Sec !. I just checked in the excellent book "Fair Game" but it's vague on this point.
