[QUOTE="J E Custom, post: 576566, member: 2736"] Lapping is always a good idea to improve the fit, But it can increase head space and effect brass life if head space is not correct. Normally this is part of the truing process and is done before the barrel is fitted. Look at the back surface of the recoil lugs on the bolt and if they are both in contact at least 50%+ you are probably ok (Not desirable but ok). If your smith will set the shoulder back and re head space then true the entire action. J E CUSTOM [/QUOTE]
