[QUOTE="918v, post: 1180699, member: 84964"] No, you would not get a split neck on the second firing, but 120% hardness does not cause necks to split. At what hardness do necks split? In my experience this happens between 10-12 firings. I dunno what the hardness is at that point. What I do know is that when I seat a bullet in an annealed neck and then pull that bullet and then size the case and reseat that bullet the neck gets harder. That little bit of sizing increases the rate of springback. So fireforming/resizing can increase hardness by 60%. [/QUOTE]
