No need to worry about a pitted chamber if you maintain the rifle correctly.
Accuracy with the newer autoloaders is amuch better than it used to be. The best overall accuracy I have experienced is with Browning BAR's, but many Remington 7400's shoot well too. In my limited experience (4 rifles) the Benelli R1 seems to be more ammo-sensitive than the Browning or Remington but once you find the right load they can be very accurate as well.
