Can I take my five-shot semi-auto wildfowling?

WILDFOWLING
Graham Downing
Although your firearms certificate may allow the gun to be used for shooting birds, the law prohibits you from using it for sporting wildfowling or shooting game.

Section 11 of the Wildlife and Countryside Act 1981 prohibits the use, when shooting birds, of semi-automatic shotguns capable of holding more than two rounds in the magazine and one in the chamber.

So a three-shot semi-auto is legal.

However, if you are shooting wild birds within the terms of an open general licence, if you are culling avian pest species, including, in some circumstances, Canada geese, you may use an unrestricted semi-auto, such as a five-shot.
