[QUOTE="Pdvdh, post: 410041, member: 4191"] I understand the OP's question to be with regard to reloading cases that have already been fired in the chamber of a [U]belted magnum[/U] cartridge. And I understand the question to be - which is preferable: 1) Resize the case so that the shoulder of the chambered casing contacts the shoulder in the rifle chamber before the forward edge of the belt contacts the belt recess cut in the chamber or, 2) Resize the shoulder of the casing back further, until the forward edge of the belt makes contact with the belt recess cut into the rifle chamber before the shoulder of the casing can make contact with the shoulder cut in the chamber of the rifle. Option #1 is preferable in order to increase case life, and to improve the centering of the bullet to the bore of the barrel. The OP made it reasonably clear that he's not asking about how to set the headspace of a rifle chamber when cutting the chamber in the barrel with a chamber reamer. [/QUOTE]
