Most of my die sets are either RCBS or Dillon. today, I stopped at my dealers and picked up Lee dies for 9x19. I will be using my R/C for this cartridge. Don;t want to mess with changing primers tubes, etc to run them on my 550. I'll be loading 9mm in small quantities. Anyway, the decapping die is carbide. My dealer suggested on the first case to lube the case-I picked up a bottle of Dillon lube. He thinks this will improve die use from there out. I never lube my carbide dies. What do GTR gurus think?
