Hi.
I'm ex UK also.
The 10/22 is on the list because of their interpretation of the factory availability extended magazine law.
The manufacturer ruger, sells magazines with a capacity over 10 rounds therefore making the rifle unlawful for jakt.
Magnum reaserch's ruger clones are also deemed unlawful based on them being clones.
The Winchester Wildcat is advertised by the manufacturer as accepting all 10/22 magazines.
Winchester only make a 10 round.
The Wildcat is approved for acquisition to hunt.
Yes there are grey areas, cracks and contradictions, but in my opinion it's much better than it could have been.
