Feenix is correct or maybe I should say give the best answer. Due to the Savage having a floating bolt head having the action and lugs squared and timed is not necessary but still a very good idea. With a remington having the lugs and reciever squared is a must unless you want the bolt engauging the cartridge crooked, which is possible. You don't have to do it but if not your wasting time and money IMO.
