So similar to what @colodog and some others have said but let me add to that.
Speaking to RCBS support, size it like any other die.
Speaking to the Sierra bulletsmiths, Partial Full Length size.
PRS shooter at my range anneals and get an insane number of reloads. Like over 100.
I have a general rule that if the brass can it to 5 loadings total, I trash it after the fifth.
I would look up Partial Full Length sizing. I made the mistake once if saying it's neck sizing with a FL die...it's not. It's how I load my belted cases
