I've had very good accuracy from Remington's Sako's,Winchester's, Browning's and Ruger's.Since every gun shoots differently with different ammunition it's really not possible to say which is the most accurate out of the box rifle.Best bet is find a rifle that fits you well and is comfortable.Try different brands and types of ammunition until you find one that your rifle likes.If you handload that's even better. You can work up a accurate load to fit your needs.With todays modern barrels accuracy is usual real good.The gun can only be as accurate as the shooter is or allows it to be.
