Do primed cases need to resized after pulling bullets?

[Hogxtz]

I have a bunch of loaded .40 cartridges that the need to have bullets pulled. After I pull the bullets, can I just re-bell mouths and reload them or should I resize them again? And if so, I assume I just remove the de-priming pin from the die, than resize?

[Divehobo]

Case size has not changed due to firing. Just run through expander, charge and seat as normal. I can not see any reason to resize

[Hogxtz]

What about neck tension? Do you think the bullet already being seated, than pulled, than re-installed without re- sizing again reduces neck tension to a point of concern? Thanks

Yes neck tension is reduced but not enough to matter. Reflare and seat bullet, crimp just enough to remove flare.

[Hogxtz]

ok. Thank you very much.

Whether neck tension is reduced enough to matter, or not, is purely subjective and depends on several variables.

I would personally reseat a few and crimp them as required. Then run them through the particular pistol by hand. IN A SAFE MANNER OF COURSE.

Load into mag with slide locked back. Hit slide release. Remove round from chamber and check for setback. If you have insufficient neck tension. Your pistol will let you know.

When I'm setting the taper crimp, I put my thumb on the rim & push the bullet against the reloading bench. If the bullet doesn't go deeper into the case, the crimp is fine.

If this was one of the answers to the multiple choice question, I would select it...

Yes they need to be resiszed. When seating the bullet it does expand the case some and you lose neck tension on the bullet. Ask yourself this question "do I really want bullet set back on 40 S&W?".

Take the de-priming pin out of your resizing die and resize all of them. Then load like normal.
