[QUOTE="Beneviolence, post: 1361758, member: 99245"] And what metallurgical rationale do you have for that? Are you trying to impart residual stresses? Produce quenched in vacancies? The only rationale I could see that makes sense would be to make sure the body of the case doesn't get annealed. Maybe I have a loose chamber neck, but my once fired brass is always larger diameter and has less neck tension than after seating the bullet (if I seat/pull compared to seat/fire). In my mind, that shows the act of firing expands it, and if it's expanding the case to the OD then it is plastically deforming the material and work hardening it. [/QUOTE]
