    The last few days I've had rounds that did not deprime but will when I put them in for a 2nd pull on the handle. Head stamp F.C. as I recall.

    Loading on a 550. The depriming pin looks fine compared to a spare pin.

    Are ya sure the pin adjusted out far enough?
    The primers may be sticking to the pin and pulling them back in the pocket just enough to keep em from falling.

    Happened a lot with my RCBS die until I upgraded to their new spring-loaded design. That solved the problem once and for all.

    I readjusted the die. Turned it down to the shell plate until it was just snug then tightened it ( did not back it off as the manual states ). This is happening to a small % of the rounds.

    Is there another pin adjustment?

    I dont know what dies your using but on most sizing dies the pin can be adjusted up and down.

    If the decapping rod is screwed in all the way the Dillon should push it off if they are the new type like their instructions say.

    I've never had a primer hang up on any of my Dillon dies. I wouldn't think that a crimped primer would make any difference as long as the pin goes all the way through the flash hole past the base of the case a decent amount.

    I've seen some WCC cases that were crimped in 9MM but have not seen any 9 MM FC's that were.

    Common issue for the decaping pin on the newer Dillon dies.... take a piece of 800 grit or finer sandpaper and knock the "squred" (squared) edge of the decapping off, making it slightly rounded. That should fix your issue. I do this with every new pin, even on my SDB.

    That was a fix I forgot about from other posters. I had never encountered it myself but it will be there in my mental tool box if it happens in the future.

    Thanks for posting that tip.

    Apparently I'm surrounded by public school graduates... or at least part time attendees.

    Teacher: Little Jimmy, what is Keynesian?

    Little Jimmy: Ah, that be where our president really be from.

    Teacher: Correct.



    I fear that we are doomed. :crying:

    Sounds like you have crimped military 9mm brass. If it doesn't punch out, it isn't gonna seat for nothing even if she pops out. I usually chuck them in the trash as it slows up my loading and in 9mm that is no fun. are you having any trouble with primer seating on those pieces?

    Keep in mind I only load pistol. I just realized it can't be crimped brass because once it deprimes on the 2nd pull the primer always seats! I called Dillon and they said the primer IS being pushed out but the spent primer is sticking to the pin and being pulled back in. He said it's common with Federal and CCI brass.

    He suggested I take a file to the end of the pin.
