Great question Coyote, I have also pondered this criteria question Myself and My list looks like this:
1. Got to shoot MOA or better
2. Relatively light weight (under 7lbs bare rifle)
3. .300 Win
4. Stainless barrel/action
5. Synthetic stock
6. Short bolt lift (70 degrees or less for much better scope/bolt handle clearance)
7. Adjustable trigger ( I like mine a little heavy compared to most at 3.5lbs)
8. Integral locking lug built into the reciever
9. Free floated barrel
10. Push feed with either AR15 or Sako style extractor
11. Screw to reciever scope mounting system, no Sako Optilok clamp-on systems for me Of course there is no rifle that features all these criteria but it would be fantastic if such a bolt action rifle did exist.....Hb
