I just switched over my Dillon 650 from 9mm to .223 for the first time since I've had it. I have been loading pistol rounds for my sons competitive shooting all year and I'm not real experienced with rifle reloading on the Dillon. My question is what length do you trim your .223 brass before running it through the press, I would assume that if I trim to speck once it goes through resizing/depriming it will be to long again? Am I off on my thought process?
