    Pulled some bad 9mm reloads using a Hornady press mounted bullet puller.
    I also own a Wilson case gauge. And every case I tested passed in it, but do I still need to resize? There still is the very slight expansion left by the bullet being seated on quite a few of them. I'd be seating them longer COAL than they were previously.

    Yes, resize them.

    Yes, you need to resize the case to restore neck tension when you seat the bullet again.

    Pull out the decap pin and resize.

    Resizing them is especially important since we are referring to an AL rimless cartridge that doesn't utilize a roll crimp to help aid in bullet hold, like rimmed wheel gun cartridges do.

    Like the others have already said, yes, resize them before seating the bullet...

    And the week before that and the week before that too.

    The problem with the search function is, if you don't ask the question in a certain way you don't get the results you're looking for. :banghead:

    Without new folks asking the same old questions, there would not be much to talk about. Look at it like school, there are always new underclassman showing up. It's our job to help educate them, not scorn them for thirsting for knowledge. ;)

    I guess my search didn't yield any results.
    I own a 9mm resizing die that is a carbide one. I still lube unprimed fired cases as it seems to make a night and day difference in terms of the resistance between the two. I've noticed already resized cases don't require lube, but what about these that been previously bullet seated? Should I lube these? Since I wouldn't want deprime these as the primers are still good, I'm not sure if the lube would affect the primer. I use the Lee case lube diluted with 91% isopropyl alcohol.

    I would just run them through the carbide and resize and then bell the mouths.

    That is supposed to be there, you should be able to see the base of the bullets in the case where the bullet expanded the case.
    Were these hanging up in your chamber or what was causing the problem? Or were they not cycling?

    You can run them through a carbide die with out lube on them. It takes more force but it doesn't hurt, if your using steel dies than they have to be lubed. That's why the carbide die was made to begin with. Just make sure the carbide die is just about touching the shell plate. Like only a couple thousands of clearing with a case in there. Don't preload a carbide die or you could break the carbide ring in the base of the die.

    Well put! Only thing that gets really old are the small primer 45 brass threads- yes it's fine to use, no, you won't notice any difference.

    You're right Walkalong. Well said. Made us elementary question askers feel better about ourselves-:)

    True. That's a confusing little widget. I believe it was Walkalong who let me in on a trick about that- you get better results if you just google "xyz subject at THR".

    It's the "which gun should I buy" threads that bother me the most...how am I supposed to know which gun you'll be happiest with when I cant even decide which gun I'll be happiest with? Back on topic...

    Sorry to add another question. But should I run the primer seating pin in my press or leave it out? Is there any danger in running a primed case over again in the priming station with the seating pin pressing against it a second time? Any chance it might actually go boom? Primers should be below flush from where I set it before, but I figured running them through again with the seating pin in, would further ensure more uniform priming depth for all the cases.

    Considering it's 9mm, definitely. But if it were me, I would resize any case that has had them pulled.

    I was already planning to resize. Did you mean yes to running it through the primer seating pin as well?
