Thread: Primer question

I doubt it. When seating the primer into the pocket, it requires a small amount of crush as the edges of the cup bottoms out on the base of the pocket and pushes the anvil up into the primer paste to set it up for ignition. If you de-primed it, it would push the anvil into the paste even further and it can dislodge paste etc. All in all, it would significantly change the ignition.
