[QUOTE="Moman, post: 328231, member: 10494"] Others will be able to answer this better than I can but I will give you a couple examples that I have had. New brass in my 308 only stretches the shoulder .002 and when I FL size it I push the shoulder back .0015 to .002 so typically I haven't seen changes in velocity. On the other hand, I have a factory 700 in 300 WM and the shoulders stretch .014 when fireforming. I also FL size this bumping the shoulder .001-.002 and if using the same recipe, the velocity really falls off due to the increased case capacity. [/QUOTE]
