I neck turn, to achieve consistent nick tension, accuracy increased moderately. I use the Hornady tool, with the Lee case holder in a 18v Drill. I can neck turn 60 cases an hour with high accuracy.
Neck turning is well worth doing. You'd be surprised the numbers of necks that are not consistently thick around the 360 degree rotation. Only Lapua are consistently in the expected range.
Winchester 243WSSM cases, both empty cases and factory loaded, are beyond credibility for uneven neck thickness, and not cut square. Necks are visibly faulty even in factory ammunition Neck turning and trimming are an absolute necessity for that calibre.
And I have seen (admittedly less than the extreme of 243WSSM) variance in neck thickness in .223/5.56, 17Rem, .243, and .270. It is a good process to undertake to ensure your reloading group have consistent neck tension.
I follow what benchresters do to achieve ultimate accuracy - and one of those tasks is to neck turn my brass. The Lee device for spinning the case for neck turning is so easy and quick to complete the task. And you only have to neck turn a case once.
