[QUOTE="QuietTexan, post: 2443124, member: 116181"] What does that setup look like? I'd be interested in a way to measure pre-seating force also. Yes, the 21st Century mandrels are floating in the similar way to how Sinclair's are. LE Wilson, K+M, Porter, and SAC are not - LE Wilson screws on, SAC and Porter use collets around a mandrel that I would assume give some limited flex, and K+M I honestly can't recall off the top of my head. The SAC mandrels are also designed to be used in conjunction with their sizing die, so the design might be a tradeoff to be functional with the neck inside a bushing rather than focusing on using separately. I agree and think you're essentially saying that while a floating mandrel does not correct poor concentricity, it also doesn't induce any. [/QUOTE]
