Never heard of that, ever Mark! Completely against HO guidelines too.
HMR and HM2 fair enough, I don't think they should be used on fox in 90% of circumstances - in fact, I'd rather use a .22lr than an HMR - those little bullets are just too unpredictable in terms of terminal ballistics.
Hornet's hardly in the same league as any of the rimfires though!!
Mind, I was told that HND in Game and Wildlife, DSC 1, and 5 years experience wasn't enough for an open ticket so not much surprises me these days! A letter to the FL manager sorted that out!
