You got a great press, I have a SD too and it's never let me down.
First thing I'd do is get some shotshell swabs and Fritz polish and clean up those dies. I do that for all my dies. A little polishing for a few seconds in a hand drill never hurts. Clean them up and lightly oil and your set.
Then, I'd get some Imperial sizing wax to start. If bulk reloading, Dillons spray lube is the way to go.
Go slow and be careful. Use your micrometer liberally. Set each stage one at a time with one round/case. Once you think it's set, do five or so one at a time to verify.
At first, I'd measure each round for powder and primer seating when going full progressive. Do 10 or so rounds, then check every third, then every fifth. Even these days, I still check every 10th round.
After 1000 rounds or so, clean your dies up, grease the main press shaft and working parts with gun oil. This is an ongoing thing to keep things working smoothly.
If your crimping (roll or taper) it may be a good thing to trim your cases after sizing so they're uniform in length. That helps a little with consistency, but not absolutly necessary.
