kdub, that's stretching a long ways for most semi-auto rifles, even with a good scope. the main one in 308 that really seems able to fit your needs is the Springfield Armory M1A in 308. these things are built solid and reliable and are pretty dang accurate. you could still get one in your price range. standard model is about $1300-1450 and they make a match grade and national match grade. these are a little higher than the standard model.
