[QUOTE="Mikecr, post: 812293, member: 1521"] Sure it does, you only need to examine the test for validity. How do you know the case necks were 'harder'? I personally doubt it. I currently run with tight clearances on a couple cartridges(one is fitted), and I also measure seating forces with an instrumented mandrel. What I see is that necks that do not require neck sizing to reload(they spring right back to dimension), never change in hardness. Necks do not thicken with firing, but with your FL sizing. Stop FL sizing, and necks remain stable in thickness. No donuts forming, no reaming needed, and no more trimming. I've burned out a couple barrels now with a small lot of brass(>30 reloads) and my originally turned necks have never changed a bit. This in 6.5WSSM. I've never had to re-turn necks in 223, 6br, or 6xc either. It's because I don't ever FL size. How do I do this when seemingly everyone says I have to FL size? They're wrong. [/QUOTE]
