[QUOTE="Mikecr, post: 1421560, member: 1521"] If you've ever measured a new -vs- fire formed case you'd know that firing does not cause runout. It removes much of it. [U]Sizing[/U] of thickness variance causes runout. The greater the sizing here the greater the runout produced. Folks, where minimal runout is desired, cull brass by thickness variance, and MINIMALLY size every aspect of your cases. Yes, custom dies are very useful for this. And, there is absolutely nothing wrong with partial/bushing neck sizing. Not only can you make straight ammo with partial neck sizing, but you're also [U]not[/U] bringing donut area into neck tension, as you will/do with FL sizing of necks. [/QUOTE]
