My advise: just shoot the rifle andthoroughly clean the bore every 20 or 30 rounds. There's no needtowait forit to become "brokenin" before youstart trying to shoot for groups. Practically every rifle I've ever owned has shotquite well from the get-go. This includes rifles that were broken in with the shoot one, clean, shoot one, clean methods and those that weren't.Now I don't bother with it.
