Of the guns you listed, I would vote for the A-Bolt, however as mentioned above you should look at the Tikka T3 (very nice gun) as well as the new Browning X-Bolt.

Between the A-Bolt and the Tikka it is a toss up, however the new X-Bolt would be my choice.
The only problem is they do not show an X-Bolt White Gold in anything but .325WSM. You might be able to get one ordered through their custom shop
