Deactivating primers

[cessna172]

I need to deactivate the primers on a few shotgun shells. I've heard that vinegar will neutralize the compound in primers, due to the acid reacting with the active ingredients. Wondering if anyone can vouch for that, and if battery acid does the same thing? My plan is to drill through the side of each cartridge to remove the powder and then inject a bit of acid into the cavity. That way the shells will remain essentially intact. Any comments?

I remember vaguely a thread about how easy/hard it was to activate a primer outside of a firearm (turned out quite difficult) that also had comments about deactivating primers.

I am sorry to say the consensus, and I am sure I remember right, was to do only one of two things to "deactivate" a primer for a round or create a dummy round:
1. Deconstruct the round and put in an already spent primer from someone reloading
-or-
2. Go to a safe and legal place to discharge a firearm, load said firearm and deactivate primer that way...

There seemingly was no known chemical to deactivate the extremely stable compounds within a primer.

Drill the hole, dump the powder and then fire the primer in a gun. If that blows the crimp off the case mouth, you can try another method.

Get rid of the primer by cooking it off with a butane torch. It will fire out the back quite fast, so be careful where you aim it.

If you reinsert the cooked primer, it will look like a virgin case, except for the powder drain hole.

Why would you bother? If it's for a collection, just put it on the shelf with the others and go from there.
