    How do I do it?

    I have a bunch on neck sized primed cases in .260 Remington which I want to resize for another rifle.

    Should I just remove the de-priming pin and neck expander? Or should I deprime as well...

    And while on the subject...

    Is it: Anneal and then size or Size and then anneal?

    I have done that some not very much though but it's pretty easy just lube the case as usual and run it through the sizing die as you normally would go a little slower the primer will pop right out. I wear safety glasses just in case but I never had one to go off,and I would throw away the used primers. If you can take out the decapping pin thats fine but you still need to let the expander size the neck on your case. Just a note sometime when your resize primed cases with the expander in the pressure can pop out the primers or move it out some so you want to look for that.

    If you will be using the same primer, just remove the decapping pin and resize. If you want to change primers, just resize as usual and the primer will be pushed out with no issues. Just catch the primers with something.

    I would anneal first because it will affect sizing.

    I don't have a problem with reusing the primer there probably fine, if it's for target shooting or plinking,but for hunting or self defense I would just like being sure and use a new one.

    What Walkalong said. Remove the decapping pin and lube the cases and go for it...

    I wouldn't anneal primed brass. Something about flames and live primers just don't seem to go together.

    If your die has a removable decapping pin just take it out and leave the decapping rod in the die. The expander button on the decapping rod is an important step in resizing.

    Sport not about to do a 'Hold my beer while I do this...' moment.
    But thank you for that none the less

    * "Should I just remove the de-priming pin and neck expander?

    All you really need do is screw the decapping pin up enough so it won't push the caps out.


    * " Or should I deprime as well...

    Leave the caps in and reload the cases if you wish, there is no harm in doing so. Nor is there any harm in pushing live caps out if you use a gentle push instead of a hard slam! Pushing them out frequently messes up the anvils a little so don't push them out and then reinstall them.


    * "Is it: Anneal and then size or Size and then anneal?"

    Not important. Just don't over anneal and make your brass dead soft. I doubt I need to caution you not to anneal with live caps in place.
