[QUOTE="MontanaRifleman, post: 853588, member: 11717"] Rich, how much shrinkage do you get when fire forming the 6.5 Sherman? Mud, you might want to rethink your OAL and neck length. Your drawing shows an OAL that is .007 longer than the parent spec. Most new brass usaully comes about .005-.010 shorter than spec'd. My Norma 300 WSM brass is .010 shorter than spec and with the 35* shoulder, it does not grow. When you fire form, blowing out the shoulder is probably going to "pull" the neck downward. How much, I don't know. But all in all, you could end up with a neck that might be 30-40 thou shorter than planned and probably at least 20 thou less. I would research this and Kiff can probably give good advise here as well. [/QUOTE]
