[Slamfire]

I was given a bucket of WW2 primed 30-06 cases. These were corrosive crimped primers, nasty stuff.

I got out my Lee decapping die, I had other choices but the Lee was vented at the top, wore safety glasses, and proceeded to remove the primer from most of the cases.

I would carefully lower the decapping pin on top the primer and slowly push the primer out.

Some cases, the primer had rusted in place. Instead of knocking out the primer the decapping pin pierced it and almost every time the primer would ignite with a bang, the cats would run for the exits in panic, and smoke would vent from the top of the die. The primer sidewalls in those cases were so rusted in place it was not worth the bother and I would toss them.

But, wearing safety glasses and using a vented decapping die, I removed about 700 live primers from crimped primer pockets.
