All your choices aren't bad and while I love a nice bolt action (preferably a P64 M70) I think a AR-10 or SCAR17 is more usefull and practical for an all around rifle. It does everything all your choices does and could also be used for defense if need be.

I have many, many rifles and I find myself grabbing my SCAR17 with a Leupold 1.5-4.5 VXR Patrol scope on it more than all others combined. Folding stock so it can be stowed in a small area, lever mounts so if the scope goes to crap I can take it off and use irons.
