briandq, don't believe what people repeat on the internet. You can reload the .357SIG without using case lube, as you can reload 38 Super, or any other pistol caliber without using case lube. Now case lube does reduce the amount of force required to cycle the press, but it is not needed, and it's a PITA to clean off. Like I said, my Dillon 550 uses standard Dillon dies for deprime/resize and seating, and a Lee for crimp. I have re-loaded over 7,000 rounds of .357SIG in 3 years for my G31 carry guns, which I only shoot classifiers with, and over 400,000 9mm and .45acp rounds since 1992, when I stopped shooting 1911's and switched to Glocks, all without case lube, forUSPSA/IDPA/Steel Challenge and 3 gun.
What do you reload?
