I know this has been said before but after realizing it myself I feel it needs to be said again.
Even if the manufacturer says you don't have to, use case lube before sizing, it helps immensely. I'm on a Super 1050 with Dillon carbide 9mm dies and had maybe 10% of my ammo not fit a case gauge. Cleaned my press, adjusted dies, clase flare, bullet depth, crimp, everything. Still not making perfect ammo. Throw some One-shot lube in the box before dumping into case feeder, and my life has been changed. Cranking the handle is sooo much easier, and ammo is way more consistent. Less friction in the sizing station translates to smoother cycles and the other stations gain from that decreased friction as well.
Gauged ~1k rounds and only had 6 rounds not sit flush.
