There was a time when your best chance of getting a really good shooter was to buy a 700. But that time has passed. Today, most of the rifles on the market are accurate. Sakos, Tikkas, & Vanguards are guaranteed to be so. Savage, the Model 70, A-bolt or X-bolt; they all shoot cloverleafs. Hell, my BLR .358 holds a 1 inch group at 100 with a good load.
