Simple test, add a few layers of sellotape to the base of a round, trimmed closely and if the bolt will close you are over sizing.

I just use RCBS FL sizing dies, set up in the "normal" way I've seen prescribed. I thought simple dies like that were hard to mess up but I could be wrong

Following die makers instructions can get ugly ! The very first thing I want to know is, where my brass will headspace within my chamber. I always want positive headspace control.
