I am getting ready to start reloading for the first time with a Lee Classic Turret press so please excuse a possibly dumb question. I used a Lee depriming/decapping die to deprime the 5.56 brass prior to tumbling. From what I understand, after resizing the brass, you are supposed to measure and possibly trim it before reloading. So what is the point of having a depriming/resizing die on the press if that's a completely separate process prior to getting to the press? I am probably overthinking or not understanding something.
