[QUOTE="Rflshootr, post: 1909521, member: 10284"] Here is one of my Lapua cases that have been fired 24 times in 222 Rem without ever annealing. The bullet isn't seated down to the donut but I started noticing the rounds chambering hard. I pulled the expander ball, sized a few and I measured the neck, then pulled an expander ball through and re-measured to find a .0035-.004 gain for about .06 above the neck/shoulder junction. Just so happens that it fit my neck turning mandrel almost perfectly. So I skimmed the neck off. And they still shoot pretty well for an old model 722 sporter built in 1952.[ATTACH type="full" alt="222 REMINGTON GROUPS 001.jpg"]195370[/ATTACH] [/QUOTE]
