The latest Home Office guide lists both HMR and WMR as suitable for fox, it is of course a guide, but if you have an issue with your region not granting fox for your WMR perhaps you should ask them why as the Home Office says its ok!
Deker, do you have a link to the latest one? Would be good to quote perfectly and send to my FEO. I was always under the impression it stated something along the lines of "less than 50yards for an experienced shot"
Basically it'll save me having to apply for a 223 and then having to fork out for another rifle, mounts, glass, bipod and pricey ammo...
Edit: google was my friend and found it immediately - https://www.gov.uk/g..._-_Oct_2014.pdf
Actually Deker, what you've said there isn't entirely accurate.
What is says is .22 Rimfires are generally regarded as having insufficient muzzle energy against foxes in MOST circumstances. However, they could be suitable for use at short range by experienced persons.
So it doesn't say .22 RF is suitable. It actually says generally its not suitable.
However, experienced persons can use it at short range.
See section 13.25.
Mathew, wIth regards to what you said about WMR, the concern is probably bullet drop as well as energy and the fact that RF doesn't have a lot of energy to impart should you miss a vital area.
Contrast that to CF, and most CF's are devasting even if not directly hitting a vital spot because of the huge energies delivered and the huge area of tissue damage.
eg. shoot a fox behind the lungs by mistake with a RF and it may run off with a small hole in the abdomen. Do the same with a CF and the sheer area of delivered energy will probably still impart heart / lung damage resulting in a fatal shot or deliver devastating shock (most likely instantly fatal) from abdomen damage if further back still. That's why RF isn't generally recommended for fox sized targets except at close range - it lacks the energy to impart huge amounts of damage if a shot lands outside of the vital chest / head area. Hence the "experienced" part of the exception.
