Get a new Howa. Known entity and if it doesn't do as it should then under warranty. It won't be pretty but will be functional. Don't get a heavy barreled varmint as you will soon get fed up carrying it. Stick a good clean 2nd hand s&ab or Swarovski or meopta 7x50 or 8x56 (given foxing as main use) and go hunting. I personally would by go tikka or sako - I would rather spend a little more and go Heym or Shultz and Larsen. Or find a good 2nd hand Heym sr20 which seem to go for c£700 at the moment.
The trouble with Tikka and Sako is they are used by professionals (forestry commission, big estates etc) and there are a lot that look clean but have shot a lot of rounds sitting 2nd on gun dealers shelves - especially be wary of synthetic stainless ones. The Heym, top end Sakos, sauers etc tend to be gentlemen stalker rifles and often shoot half a dozen deer a year and can be real sleepers. But you need to know w what you are looking for.
As I said at the start, go with the new Howa.
