not sure about answering this one - everyone has different priorities! when choosing what to buy ( finally opting for a T3 varmint), i looked for things that would give me accuracy. so free floated barrels are a requirement. a stiff action is usually conducive to accuracy, so i liked the single column magazine and narrow ejection slot of the tikka. the bolt cycle is as smooth as silk due to the one piece design ( try a CZ mauser type action for comparison! they are gritty and prone to binding).i was viewing things from a small calibre, varmint rig viewpoint. if i was hunting big game, i'd want the bigmauser extractor.i was not fussed about hammer versus button rifling. you can get dud ones either way. most benchrest custom barrels are button, though........
knurled bolt handles are completely irrelevent for me, but for cold area hunting may be advantageous. bedding is critical - especially for timber stocks. look for some form of pillar bedding. you will probably find that getting all your requirements is either not possible, or will cost heaps. compromise on whatever you consider to be non-critical issues for your hunting type, but stick to your guns on what you want. and bare in mind that there's no point being unhappy with a purchase for the sake of saving a hundred bucks- you'll just be looking for something else a few months later.
