700 PSS in 308. I had AZ Precision put a new knob on it, mounted a Sightron SIII 3.5-10 on it, adjusted the trigger, and commenced to shooting. Built a reload for it and shot it some more. Figured out the drop and wind for 100-600 yds and shot some more. I think I do ok with it.

I have an AR set up for longer distances, a DPMS 24"bull barred competition upper on a RRA lower with match trigger. It does ok too. Have a Winchester Laredo in 300 and a sendero in 270, but they're not set up with the right glass yet. They shoot pretty well also.

My experience is as long as the gun will shoot half MOA consistently, it's mostly the shooter and the glass after that. I'm not as good as a some of the shooters on this site, but there's a lot to be said about burning out a few barrels to get you there.
