I bought the set and found the instructions to be unclear. So i called RCBS and asked and what i related whas how it was explained to me.
With that said you can tune how you use the die, it gives you options. I trim to the specified trim to length in the manual. After firing i size 1 piece twice. So a full size, then back up into the die and set the mandril to that length, so it should keep the growth uniform. Accepting that i may have to trim my brass twice during its life.
But it gives you options to eliminate or reduce trimming, and im all for that.
