Why not use expander balls?

[QUOTE="Mikecr, post: 897182, member: 1521"] I partial NS with Wilson bushing dies. I can adjust the length of sizing with shim washers(machine bushings), which I do as part of fine tuning during load development. The carbon film in fired necks is perfect lube as it is. After vibratory cleaning and neck sizing of cases, I run a turning mandrel through each neck and watch the force required to do so. If hi/low, I can affect further readings up/down either with an expander mandrel(+1thou), or higher/lower length in neck sizing using a different thickness die shim(instant change with hand dies). I typically load 50rnds at a time, and out of measure I typically set aside ~6 or 7 to tweak on. If it goes beyond this(becomes a burden), it's time to consider a reset with annealing. Another subject, but: To have control over actual bullet tension you need to have control over springback, which means you need springback. Annealing can greatly reduce springback, and this can remove control over it. Annealing does 3 things: It increases seating forces AND reduces bullet tension AND affects your control over it otherwise. With this, your tension and consistency of it comes down to the precision in your annealing. So if you're going to do it frequently, I recommend you invest in the best available process for it.
