[QUOTE="QuietTexan, post: 2331103, member: 116181"] They're very enlightening, both in the quest to be as anal-retentive as possible, and also as reassurance towards letting go and doing less sometimes, because everything doesn't always matter. The expander ball pulls back through the neck to reopen it (as Petey mentioned before), and it's pulling back upwards at a point where the shoulder isn't supported against anything and as it pulls it can pull the shoulder/neck out of concentricity. Your mandrel will work the same way as it does now if you remove the ball, you've probably been straightening the necks without knowing it with the extra mandrel step. The basic process is to leave the neck as sized by the ball and seat the bullet into that fit, which can cause significant runout. Hornady makes a smaller barrel nut to hold the decapping pin to the stem, they ship with neck sizing die and (I believe) the match-grade bushing dies. Probably something you can get ahold of just by calling them if you don't have one, or you could use a smaller caliber's button. I usually decap with a Lee universal decapper earlier in the process than sizing, but not always so I keep the smaller nuts around for when I don't. [/QUOTE]
