[QUOTE="Mikecr, post: 1239777, member: 1521"] On more thing; When you FL size thickness variance it causes outright bananas, and all the neck work in the world will not really help. Variance, and sizing of it.. Whether it matters to results depends on chamber clearances. If high, runout matters less, even while this leads to greater sizing -which leads to greater runout. A cause/affect loop that is fortunately forgiving. Where clearance are tight, you can produce truly straight ammo. But where you've caused/introduced runout anyway, you're more likely to see degrading performance from chambered tensions. A case pressing a point hard in a chamber is just the same as pressing hard against any other part of the metal system. It throws shots. It's a reason some folks see FL sizing as practically required. But it isn't always. We can make straight ammo, with less effort, that shoots fantastic, where a well implemented plan reduces or eliminates sizing requirements. Another cause/affect balance. Just takes an early plan.
