Just had a few minutes to open the B.A.S.C. mag, a small piece of interest, "There is no legislative obstacle to using any firearm for fox control, unless prohibited by a condition on your firearm certificate, foxes fall within the definition of "vermin" and no court has said otherwise. If "vermin" are featured in the certificate condition it is lawful to cull them with a rifle. However using an air rifle or a calibre which was likely to wound a fox rather than achieve a clean kill could lay you open to prosecution under the animal welfare legislation. For best practice advice about the use of rimfire rifles please contact B.A.S.C.'s firearms department.
Hard to make use of this nugget of info when some police forces don't seem to agree with it! .................. wonder if anyone could take up the sword on behalf of those of us who are denied the rule of law?
