I'll back up what VA27 says, I had a 308 VS that was giving me 1/2 MOA out of the box. I lightened the trigger to 3 lbs, and it was just about perfect. (I only sold it because I was strapped for cash.) 100 yards is not 1000 yards, but if you can't keep it tight at 100, there is no point in getting serious about 1000 either.
About a year ago in one of the shooting shows on the outdoor channel, they rebuilt a 700 from scratch, started with a damaged rifle, stripped it to the receiver, jeweled the bolt, squared and mounted a new barrel, lapped a target crown, etc. I was fascinated, but at the same time, I realized that this is a process it takes more than a corrosponence course to learn correctly.
Keep in mind, if you're serious about accuracy, it's more than just the rifle. You have to be prepared to break in the barrel, size your chamber, try a variety of handloads until you see what that rifle shoots best. The rifle is really just the beginning.
