not strictly true , my friend applied for his FAC and yes it only showed one piece of land , another farmer had a fox problem and my friend called his FEO and asked for the restriction to be removed , they said no but they put the land down as a temp pass and also stated they will do the same for any other land he wants to shoot on aslong it has been passed for that calibre.
to be fair your not making great gains by using an FAC air rifle and in my eyes is only good for one thing which isnt legal.
call your FEO , you will be surprised
