There you go with the worrying. Nothing about the primer is Ferris metals,so no sparks unless you stow you fire starting flints with them. Wink

Am I missing something?

Primer packaging is designed to prevent ignition propagation between primers in the same box. Those nice little black trays they come in aren’t just for neatness. That is how we can ship them without a Class 1 (explosives) designation. The packaged units undergo extensive testing in their packaged configuration including drop and bonfire tests. All of these are required by the DOT via the 49 CFR (Code of Federal Regulations). Basically, DO NOT store your primers loose in a container.

Even if an entire sealed can of primers got caught in a house fire, they would not all initiate simultaneously. Plus, ammo cans are pretty flimsy when it comes to containing internal pressure. The can would deform and vent before violently exploding in such a situation.

Either way, there is nothing wrong with a cabinet or cardboard box for storing. The main thing is to keep them clean and dry.

Static is only an issue with loose primer composition (which can build up where you least expect it!), not with whole primers.

Which is why Federal trays and boxes are larger than other brands. Federals really are more sensitive.

NFPA 495??? Recommends storing primers at least 15 feet from powder.
