On my Hornady LNL AP, I'll have maybe 50% of the brass (9mm) on the first station not line up perfectly on the decap/resize die, requiring a little nudge from my finger in order to go in. This happens less frequently on my Lee Classic Turret press but it still happens. It's so common that my hand naturally comes up to the brass as I raise the ram in anticipation of needing to guide the case. The shell plate is indexing correctly so that's not the problem.
Anyone else experience this on their press?
