[QUOTE="J E Custom, post: 885874, member: 2736"] Everything has to be squared to the center line. The bolt is squared by turning the back of recoil lugs and the bolt face in the Lathe. Then the receiver face is squared and the recoil lugs are squared in the lathe at the same time. then we lap the lugs to seat them and polish the mating surfaces for smooth operation and extraction. In order to be able to work the bolt there has to be some clearance between the bolt and the action, Proper head space and a good chamber will solve any alignment problems due to this built in clearance. In My Opinion, It does matter if the bolt is not square. The reason being, the bolt can move during firing and if it is not square to the recoil lugs , The bolt face can cock the case head several thousandths hurting accuracy and case life. Note: If everything is not square it does no good to do some of it, and in some cases it can make the condition worse. Just my opinion J E CUSTOM [/QUOTE]
