How to KILL Disable a Primer

[hat674]

I need to disable some primers to put into Dummy Cartridges that We are going to make from some Brass 12ga Shotgun Shells from WWII. We want to Clean the Cases up put a disabled primer in, A Lead Slug and Laser Engrave the Case to make a display 12 ga Cartridge.
Thanks

I wouldn't trust a liquid or solvent to do it.

Not if it's important (is it? Really?)

What about putting the primer in the case, heating it over a stove until the primer pops? Then polish it so it looks all new and shiny and has a good-looking primer in it w/o dents (no firing pin strikes)?

What's the big deal if the primer is live -- especially if you're talking about a huge 12 gauge case with a lot of volume in there?

You don't think a primer could push a 12 gauge slug out of the barrel do you?

Alternative idea: spray the primers with WD-40 which has a reputation for killing primers but may not be 100% reliable. Then seat t hose primers into the cases,
fill the cases with kitty litter or some inert material, then load your slug and crimp it.

"
The only sure way to de-activate primers without “firing” them, is to use Vinegar and let it sit in the bottom of the case for over night, then wash out with warm water…
The Vinegar will dissolve the Lead Foil seal of the Primer, inside, and then react with the priming compond, deactivating it and making it soluble to be “washed out” with warm water and detergent (soap)."

Mechanical deactivation of primers

mausernut, In Russia we too have law requirements to fire the primer and to drill a case, but we have legal paradox which allows us to avoid problems. The Russian law tells that a cartridge it “set of gunpowder, a bullet, a primer united by a case”. Accordingly, if the cartridge has no one of...

Why not just take a spent primer, place it in a hard flat surface like the anvil plate on a bench vise, and use a small punch on the inside to flatten the cup back out? Then you can polish and seat it back in your case

Was about to say this.

A drop of oil will kill it

Just pull the anvil out and set it as normal.

Why not get a brass rod of the same diameter as a primer, cut it into the correct length, and press it in the primer cup?

This is part of the process (with a new compound added omitted) we tested back in '93 when the rumor mill was going full tilt about how the goobermint was pushing legislation to require primer manufacturers to make them with a "shelf life" of something like 90 - 180 days. You couldn't find a Strike Anywhere match within 200 miles of Greenville, SC. This was way, way before white people started cooking meth on a large scale.
