Shelf life of primers?

[GT1]

I have seen them go off after being soaked in motor oil for a couple days.
The best way to dispose of them is to load them and shoot them.

if the primers are on the shelf they don't last very long, they get loaded into ammo and shot up in no too much time

GT1, since you’re new here you may not understand why we use the “cartoon” name “boolits”. It’s an easy way to differentiate whether cast lead or gilding metal jacketed is the subject. Boolits = cast; bullets are jacketed.

Apologies to everyone else for hijacking the thread.
