I use a Mighty Armory decapping die for processing brass. I like the Dillon sizing die except for the e-clip breaking on the decapping pin shaft holder after a while. The Mighty Armory decapping die is more robust at this specific function, and is universal for the calibers i reload. If the Dillon e-clip breaks the pin/holder falls out the bottom destroying my brass/press on my automated system. The dedicated decapping die does not have this problem due to a better design. So far I have not had it break in the 6k rounds processed. Win win. I used to have the Dillon e-clip break in about 2k rounds.
