Annealed Primers?

There's a very old story in one of the Brownells "Gunsmithing" books, about someone attempting to
make dummy rounds by firing the installed primer with a propane torch.
Story has the primer fired out of the pocket with enough force to pass trough the bicep and lodge
against the bone.
Must be true; it was a half century before the Internet.
 
You know that I'm a slow learner, right? However - I can assure you that, through Careless Experiment, that, using an AMP:

1) You can normally get away with annealing primed 308, similar and larger.
2) 6BR primed brass will mostly be OK - but you will be unsurprised to learn that some will go off as the heat conducts through the brass, in the cooling tray, causing brass to scatter
3) You had better wear gloves if you anneal primed Grendel brass, for the first and last time.
4) Careless Experiments have not been carried out with 222 or 223 brass.

Not true
It’s one reason I load up my giraud , point it in a safe direction
And walk away
I’ve annealed several primed pliers of brass and one 223 round that had a bullet shoved in it I missed so there was some powder
Primed brass just pops
Blows out the flame
The round threw brass everywhere
No damage to the machine at all

My procedure for annealing is always tumble the brass first
Load the annealer looking at each case mouth
Start it up
Walk away

You think maybe your procedure should include looking at the end of EVERY piece of brass before loading the annealer? Can't believe anyone would have it happen more than once! Jmho.

Better your AMP than mine...;)

I was looking for primers and saw some “annealed primers”. Never heard of this. Anyone know?

I was I a reloading room with a friend that tried annealing some of his primed brass and one went off and then caused several others to go off in the metal catch pan under the trap door of his annealer. Needless to say, I don’t go to his reloading room anymore.

OLD POST WARNING.

The mouth of the prime is annealed softer, to seal the pocket from gas leaking.
This started with large 16-inch bag guns, to stop gas leakage that damaged parts.

This post led me to search for info on the primer used to ignite the 16” powder bags. Details are provided starting a little before the 2 minute mark.


I’m not sure which (perhaps both?) of the primers were annealed!
