Hello all. I'm relatively new to loading for the 10mm. I started my loading career with .40 minor for production division competition and after having my gun choke on some "glocked" brass I got the U-die. That's what's setup in my dillion at the moment and I was wondering if anyone has used it to load 10mm. I was thinking to just move my seater and crimp dies up a bit (redding competition seater and Lee adjustable crimp die) and the only die I'd actually have to take out of the toolhead is the powder die to adjust it to the longer length. Anyway, the U-die will squeeze the case a bit smaller. Has anyone used it for 10mm and had any problems with case life?
