Savage, unless you're willing to spend more $$ to have the action trued. I'm convinced Savage's floating bolthead has at least something to do with it...
Look at their Model 12 LRP. Uses the target action, target Accu-Trigger, and HS Precision stock in either .260 or 6.5 Creed. If I had a grand to spend on a rifle, that I could take out of the box and shoot at 1K, this would be it.
Not knocking the 700- it's just that it might take some more work to get it there. The 700 also has more aftermarket parts support, though Savage is no slouch there, either.
