Here in the UK I've never personally seen any CRF rifles in medium game calibres used for hunting. The only ones that one sees on forums are old Parker Hales. In fact, excepting my own Win70 (where I specifically searched for CRF as it was a .375) and old military rifles for classic military rifle comps, I've only ever seen 2 other CRF rifles full stop.
Most (80%+) hunters opt for a Tikka T3, a Sako 85, a Rem 700 or something like a Scultz and Larsen or a Blaser. Maybe a few opt for a Howa, a Browning, a Steyr Mannlicher or a Mauser M12.
Honestly, unless its a DG calibre, CRF offers no real benefit for hunting in my experience and it seems that the market agrees.
