The action on the 700P should suffice, really. As many have stated, at that distance, it's not so much the gun, as it is the shooter. I'd imagine optimally, you'd get a Custom Action, as those are expensive for damn good reasons, but really, the 700P or a 40-XB should cut the job. Although, more of a Concern is what round you are using. A .308 is kinda iffy at 1000 meters.
